Asus P8Z77- V
EVGA GT 430 1GB
8GB Patriot Viper 3 1600MHz
Corsair CX600 600W PSU (if power is an issue)
And I'm trying to look more into Nvidia because Radeon drivers are known to have major issues especially in Flight Simulator X. That's the game I'm going to be playing most of the time. (Well there is the occasional Nazi Zombie massacre in COD 5, but that's not too demanding.
Anyway thanks for the replies!
I'll likely be waiting a few months before I get a new video card anyway so that gives me more time to think about it. I saw the 660 but it seems to be overpriced at the moment.
One other thing, I want to be able to take advantage of PCIe 3.0 with a GTX 600 series card, if that makes any difference. If a 500 series would perform better, I could care less about PCIe 3.0.
