Thats $462, I think you could squeeze in a UD3P for crossfire later. but, you would need to upgrade the psu.

I wouldnt cf 2 low end gfx cards though, wait to get a good card and a good board, then cf.

Also, check into the 4770's. They seem to be out of stock..

What about the OS?

You could put it in a combo deal with the 640gb hdd if you dont have vista 64 bit.
