Thanks for the quick replies everyone!
I'd like to run the full res of my monitor, 1920 x 1200.
So I'm thinking this card then:
EVGA SuperClocked 01G-P3-1563-AR GeForce GTX 560 Ti (Fermi) 1GB
NewEgg has them for $230 after rebate. I've had good success with EVGA in the past. Do you agree or like a different 560Ti better?
