Hey guys, I've been looking through the market for ordering a new PC here in the next month or so. I want to run WAR at max settings for the next few years

. I'll also be using CAD applications like Solidworks and Autodesk, for school.
I've made a computer on buydirectpc.com and my specs are below. Let me know what you think.
The main reason I'm posting here, is to search for advice on how to save money. If anybody knows a much cheaper road for me to go (another site to look at, or comments on building from scratch), then any comment will be helpful. Currently this pc will run me about $2,200 with Vista 64-bit.
Thanks for any comments/advice you can offer!
