I think spaceloaf covered it quite nicely. I'm looking at a Gigabyte mobo myself, but only because of cost. And I'm not seriously looking. ;\)

I really like my Corsair HX520W. Seems quite capable.

I also like my x1950Pro. Last generation, but it seems plenty fast, and it was a good price. That said, if I was buying now, I'd get the 8800GT.

I am the Doctor, and THIS... is my SPOON!
