So I'm a freelance Editor/Motion Graphics guy with no real understanding of RAID Controller Cards, or how they work.
As of right now I have three 1TB drives inside my Mac Pro, RAIDed together (stripe 0) using the OS. No Raid card.
The drives are all 7200rpm from varying manufacturers. (not sure if this matters.)
My questions is; is it beneficial for me to get a RAID card to control these drives vs. leaving it to the OS to handle? Any suggestions for me?
Thanks.

It all depends on the details of how you use the system (RAID is supposed to be configured to the specific usage, so there's no "one size fits all", though for narrowed usage patterns, you will see similarities).
I'd advise you to search out previous RAID threads (there's quite a few), and pay attention to the various questions asked, and get back to us with some answers). I'd also recommend you review Wiki's RAID page (http://en.wikipedia.org/wiki/RAID) (pay particular attention to the different levels).
If you're a paid professional, using a stripe set (RAID 0) is a disaster waiting to happen. Even with a backup, you'll spend a fair bit of time to perform a recovery when a disk dies (matter of when, not if), and this also means re-performing work that was done between the most recent backup and when the array failed (beyond replacing the bad disk and restoring all the backup files, which presumably <worst case>, will be multiples to return all the data you have from your backup media).
Glad to see you at least have some sort of backup with your current configuration. :)
Now if you go with a RAID card, you'll need to use enterprise grade drives for stability reasons (different recovery timings in the firmware than consumer models, which tend to be unstable as a result). Unfortunately, they're not as cheap (in fact, can be 2x as expensive as their consumer counterparts for the latest capacity).
Consumer disks are fine for backup purposes though, and this can save you a considerable amount of funds, particularly if your capacity requirements are high (i.e. eSATA card + Port Multiplier based external enclosure; example kit (http://www.newegg.com/Product/Product.aspx?Item=N82E16816111136&cm_re=tr4mp-_-16-111-136-_-Product)).
There are some inexpensive products that claim RAID 5, but be careful. Some are software based, which should never be used for this level (no solution to the "write hole issue" associated with parity based arrays). Others use very inexpensive hardware RAID controllers (aka RoC = RAID on a Chip). They're slow for primary usage, and is why they're cheap (compromise on performance vs. proper RAID cards).
If on a budget you could go with RAID-Z, it involves switching to the ZFS file system. RAID-Z1 apparently offers similar performance to RAID5. Read this thread (http://forums.macrumors.com/showthread.php?t=1135718) for further insight.
This can get complicated on the software end though, and not recommended for those that aren't comfortable with the additional complexity (patches for OS X or via VM), particularly for a DAS system (has more merit with NAS or SAN IMO).
So I'd stick with a 3rd party hardware RAID card, assuming this is actually needed, enterprise disks and any enclosures/mounting hardware necessary. Much simpler in terms of software (install the drivers, and any interface software that's required to access the card settings), and the hardware aspect isn't that difficult either.
I would get an SSD for the OS and use the 3x 7200rpm Disks in RAID5.
RAID5 is great for storing uncompressed video data and in your case would offer protection against a single drive failure.
Most cards don't deal with consumer grade disks very well (ATTO and Area definitely don't).
But consumer disks are fine for backup purposed (i.e via eSATA and PM enclosures) due to the lower duty cycle (where you can cut costs effectively, and not endanger the data).
or Just RAID5 with 3x HDD's and partition the RAID volume.
I wouldn't do this if both partitions are to be used simultaneously (i.e. primary data one one partition, scratch data on the other).
The most recommend cards right now are the Areca 6g 1880 series or the new ATTO 6G series. For your needs something like the ARC-1880-i SAS 6G RAID Controller would suffice if you don't plan to connect external RAID/Storage solution.
Those are the best recommendations as far as brand and series per. As to a specific model, it will depend on the specifics, particularly for growth (i.e 8 ports may be outgrown in under 3 years, so getting a card with sufficient ports to last that long would be cheaper in the long run - just add disks and enclosures as necessary).
Sorry should have been more clear (like I said I'm dumb) I have a 500GB Boot drive that lives independently from the (3) 1TB drives RAIDED together via the OS.
A separate boot disk is advisable, as you still have a working OS if the array goes down (allows you to access the card, use the browser to search for help, or deal with Support from the card manufacturer if needed).
And ALL data (3.5TB's) is backed up by an external 4TB Time Machine RAID (2 drives @ 2TB each)...which is connected via 2 eSATA cables via the eSATA PCI Card I bought from OWC...which I guess is actually RAIDed by the OS as well.
That backup solution is a RAID 0. The overall backup solution will almost certainly need to change in order to be sufficient for the primary storage pool you'll end up with.
Not sure what you are looking at, since 3 drives is sort of an odd combination. I have a 2009/2010 Mac Pro Nehalem, running the apple sas card for the 4 internal bays (yes I know they make adapters to use 3rd party cards), and the performance is fair, not great but fair. About 300Mb/s read/write with 4 WD Black edition drives (1tb each). Externally, running an Areca 1680x card, with a 8 drive ProAvio chassis, 8 SAS Seagate 15k7 drives (450GB) which gives close to 900MB/s. I have tried multiple cards over the years, nano and I have exchanged lots of posts/messages. Email/PM me with specific questions and I will try and help you. Beware of most of these 3rd party slot adapters/etc. they are more hassle than they are worth.
I've not heard or seen any issues with the MaxUpgrades kit.
As per Apple's card, I'm no fan of it, particularly due to the cost/performance ratio.
BTW, the OP only has 2 posts at the time of writting this, so returning a PM isn't possible yet (needs to have 5 posts IIRC). email would work if you have that enabled.

What is blank screen mode? I don't run mine in screensaver mode, I turn it on and set my computer to stay on and just shut off my monitor.
**edit**
And I'm pretty sure that seti units are always the same size, its folding ones that aren't.
Yes, they are all the same size but the amount of processing required to complete the task differs from unit to unit.
My G5 did a work unit in 45 mins one time. On average it takes less than 2 hours / unit :D. The command line app would be even faster.
I don't run it any more as it apparently rips hard drives and I couldn't be bothered setting up the RAM disk method. It also turns my G5 into a bit of a wind tunnel some times.

I tried to include the .h file through #import <Fraction.h> directive but I get compiler error "No such file ore directory".
Look in your book for exactly what you're supposed to use for #import. You may have made a mistake.
I'm not sure, but #import <Fraction.h> seems wrong to me. If Fraction.h were a system-provided class, it would be correct. But it's a developer-created class, so #import "Fraction.h" seems more sensible to me, and is what I've always used when referring to class headers I create.
I am sure that there are no compilation errors in the Fraction.h and Fraction.m.
Post your code.
No one with any programming experience would believe anyone (beginner or experienced) who says there are no compilation errors, unless the code has actually been compiled without errors. You may be right, but we need to see the evidence of the compiler.

I started folding with the G5 home computer for several reasons. First, I leave my computer on most of the time and really like the idea that for pennies I can have an application working on something useful for other people. Since I work in...<gasp>...IT, I also like the idea that processor time there is serving some higher cause.
I also lost a family member to cancer, so there is some small motivation there to see if some cumulative work will help in the understanding of these diseases -- though mortality is part of living....
Another reason? To contribute to the MacRumors Team (http://vspx27.stanford.edu/cgi-bin/main.py?qtype=teampage&teamnum=3446) effort and earn props for the team.

Your answer helped. So now I know that <**> are only for system provided classes.
Actually, <include.h> is for headers that are found in the -I include paths specified in the CFLAGS var usually with make. You could add -I/path/to/your/headers to your GCC command line and then #include <yourheader.h> just like any other "system" include. #include "yourheader.h" includes headers either with an absolute or relative path to the current working directory of the compiler, which when using a make based system, happens to be your source directory.
Just some extra info there for you.

I too have been using Mactubes, and it works better than the in-browser flash player, but I can't seem to get quicktime to work.
"Can not open video. Please open URL with browser."
That's the error that I get when I switch to Quicktime. Any ideas?

Not sure why you didn't just call Monoprice and ask them, and the product page itself says "does not support audio"
Not sure why you didn't just move along instead of posting a snide comment. I read the product review and saw a variety of answers. I came here to confirm them
I have a Monoprice adapter that DID NOT carry audio, just video to my TV from my i5 2.4 MBP. You have the same generation MBP, albeit a 2.53, so your mac has that ability.
I ended up picking this adapter from Amazon:
http://www.amazon.com/gp/product/B003CK8TZ8
This one will carry audio & video. Works perfectly and looks pretty cool too. Not as cheap as monoprice, but does the job.
I read that you have to go to sound in system preferences and change the output to tv once you hook the cord up. Can you confirm that works?

As long as you sign up to be a safari developer (for free), then you are officially a developer to apple and can access the videos. So it is free to watch all of the videos, all you have to do is sign up with the safari development program.

Wait, hang on. Was this supposed to be a FREE printer? If yes, then I can see how you'd be upset... otherwise, it's possible they just ran out of them and can't get anymore within a reasonable timeframe. In that case, you can hardly say that you were gypped; if they're only charging you for what can be delivered to you, that's correct behavior.

congrats on the switch! first thing i always do is run Software Update and download any updates you need. there should be a bunch depending on when your machine left the factory. after that you should run Disk Utility and fix all permissions. then i like to setup my preferences and go. maybe import your music from another machine. unless you're really in love with partitioning your HD then go for it but i think you'll find that the standard system setup is capable of keeping your machine very organized. you'll see. enjoy!

How do you use the knife part, and how does it not slice your mouth open?
I suppose the knife part is on the side and I guess you just have to be careful not to cut the side of your mouth open. I doubt its that sharp tho. I'm yet to use or to find one of these in the wild.

The OP stated iLife 11
There were multiple iPhoto updates for the version in the iLife 11 suite.
It's similar to asking 'what version of OS X are you running'- even if OP already said Leopard it would be necessary to find out what specific version he's running (for example, 10.5.2).

a cool key combo i accadentially discovered not to long ago is the command + ~ this will cycle through the open windows of the current program. so if you have 3 windows in safari open it will only cycle through them and not go to another program.
Actually its the ` not ~, since ~ would require the Shift key :D
Here's a bunch more you can accidently discover too ;)
