New Mac Pro Tower Configuration

Question

Hi
I am currently looking at purchasing a new Mac Pro Desktop Tower to run CS 5.5.  I am planning to use it for longer video projects with premier and AE.  I would also be using audition to some extent.
I don't think that I can afford to go with a twelve core version of the Mac Pro, but I am wondering what is the best way to configure the ram/processor/video card?
Also are there any compatability issues with OSX Lion?
Any help will do.
Thanks

While the case for building a PC is strong and valid, and while I would build a PC if I needed a new system right now, I also understand the needs of some institutions to build a Mac. Here is my advice in that regard:
1. You don't need dual processors. I have a single 6-core 3.33GHz chip in my 2009 Mac Pro (which I upgraded myself) and it handles heavy work in Premiere and After Effects CS5.
2. Don't buy any RAM from Apple. With the price of hard drives today, it isn't such a big deal to have Apple install extra drives for you, but if you're even slightly technically inclined, you can install more RAM and hard drives for less if you shop and buy from other vendors. There is a great Mac-specialty website where I buy my RAM from called OWC (Other World Computing link) that has excellent deals and service. I think 24GB is minimum ($322), and 32GB is better... only $425 right now.
3. If you have the budget, a proper third party RAID card is a much better deal and performer than Apple's Mac Pro RAID Card, so don't waste your money there unless you really want to limit yourself to an internal RAID 5 of no more than four disks. I got by with a 3-drive RAID (AID) 0 stripe of disks for a year before needing to expand to a proper RAID. With three Apple drives striped together, you'll get a sustained data throughput of 330MB/sec both read and write speed, which is good enough to edit some HD video. I edited a feature-length film shot on P2 at 108060i/24p using only three internal Apple 1TB disks, with backups to external drives holding a safety net for my data.
4. You don't need to buy an NVIDIA /CUDA card (Quadro 4000). I have the 5870 from Apple, and I can edit DSLR 5DMkII footage in smooth real-time, but that is helped by the 32GB of RAM and fast RAID. I have a CUDA card, an older GTX285, and while it was good for Premiere, I felt it was slower than the 5870 in After Effects, which is where I spend more time rendering anyway.
I'm not sure how much weight you'll be placing on student projects being safe from loss in the event of a drive failure, but you could either have them back their projects up themselves on their own external drives, or build a robust RAID. I have an Areca RAID card that runs eight 2TB disks in RAID6, which yields 12TB of very fast data that is also still safe if any two of the eight drives fails before being replaced. Depending on the number of students using the system, it could cost less to build a similar RAID than have each student buy their own drives. Question is, does the school eat that cost of security for the students, or let them shoulder that cost themselves?
I was a film school student myself, and I know what it's like to sign up for a four-hour block on a limited number of edit suites. You want the system to run faster than the students, so they can be creative without wasting their time slot waiting for the computer.
With your education discount from Apple, you should be able to get a 6-core 2010 Mac Pro, RAM, disks (and RAID if you go that route) from 3rd parties about $6000... much less if you skip the RAID system. If I can help in any way, let me know. I love my system, even if I could build it in a PC today at half the cost. Adobe works the same (or better) on a PC as it does on a Mac once you're in the software, but if you have to go Apple and can't wait for what may come out in the future, consider a system like mine.
2009 Mac Pro (updated to 2010 firmware... you'd buy a 2010 and not worry about that.)
3.33GHz 6-core CPU
ATI Radeon HD 5870 (still runs software acceleration very nicely)
32GB RAM @1333MHz
(4) internal hard disks (1=OS X, Adobe CS5, 2+3=RAID0 (stripe) for scratch files, 4=other backups and storage)
Areca 1880ix-12 RAID card
Sans Digital 8-bay tower
(8) 2TB WD RE-4 hard disks in RAID6 = 12TB parity array (sustained 816MB/sec write, 714MB/sec read speeds)
Various backups in external disks.
Good luck!
