I use 1600x1200.
2gb or ram
current video card: GeForce 8600 GTS
power supply: AX500-A 500W
So the question is what video card, if any, can I get to bump up performance?
So. I upgraded my gfx card to an ATI HD 5770. Figure that's enough for a bump.
Do you mean you already upgraded to an ATI HD 5770? And yes, that is enough for a good bump at your resolution.
