Well I managed to find one in stock and the 8800GT is an amazing medium. http://www.newegg.com/Product/Product.a ... 6814121099 but on the side of saving money http://www.newegg.com/Product/Product.a ... 6814130290 there you go.
In regards to the case, you are on your own, personally I'm not a fan of much except Lian Li and Silverstone cases, but those way break the budget.
Finally Vista. To be honest you don't need ultimate. You will never use half the features unless you are setting it up to be a server, or as part of a business. You would be fine with Home Premium x64.

Ah, So premium does run at 64. Couldn't find anything that said it did. I'll check newegg for the stats. Thanks for the links on the cards. May do the 8800 now.
