Configuring a Mac Pro

can anyone suggest me the minimum sata-ii hard disk, need to upgrade my desktop that has 400 gb sata hdd, as I am currently having online lessons in a range of adobe photoshop, premier pro, illustrator, auto desk maya, corel draw and various others including a few CAD softwares that my brother would be using. I am looking at a range of 600Gb to 2TB here with either 5.4k rpm or 7.2k rpm, I suppose 7.2k rpm would be faster readable, but on volume side I want to keep myself to the lower range since my most priority upgrade would be graphics cards & rams, and do not have much budget to spend.

I will often have InDesign, Illustrator, and Photoshop opened at the same time. Illustrator files are usually complicated with many layers. Photoshop files can be 500 MB or more. I plan to purchase the Mac Pro 8 Core http://store.apple.com/us_smb_78313/configure/MB535LL/A?mco=NDE4NDIyMQ Can you make recommendations on which processor to choose, how much memory to purchase, and which graphics card to buy, plus anything else you feel worthwhile knowing?  I want the machine to last 3 to 4 years. Thanks!

Disregard the man behind the curtain (first answer you received). Follow the directions of the second answer you received. If you planing really serious work get a Desktop model with the fastest processor and a minium of 8 GB RAM, Getting Machine configured this way should come with a minium of 500gb Drive (approx).  The Drives are SATA and actually plug in you can actually use up to 3 Terabyte of Hard drive space. Also choose the Nvida  Card with the largest on board video RAM. (512kb-1024mb) The System RAM comes in Matched Pairs and capable of using up to 16GB.
