What Machines to Buy Now?

The question now arises, what machine to buy for all this 3D stuff. This from one of our customers

“We just ordered 12 machines: They’ll all be 64 bit with Windows 7 Ultimate loaded… 9 gigs of ram, 10,000 rpm Raptor hard drives, and NVidia 260 video cards with 1.8 gigs of ram on them”

This sounds great to me. Now that the Vista horror show is over, and we work on 64-bit operating systems, it's a good time to take advantage of what is out there.

Now, if he would just send me one to test for a couple of years, I'd be happy...
