I currently have an ASUS Striker II Formula nforce 780 SLI mobo with a Q6600 core 2 quad CPU and 2 8800 GTS 640mb in SLI. I was wondering if it is a good idea to upgrade to an MSI GTX 560-Ti Hawk, because I can play Crysis 2 at Extreme resolution with no problem...I just can't use the DX11 features. Anyway I want to prepaer for BF3 and I need to know if I can just upgrade the video card or if I have to upgrade my entire PC. Thanks for the advise!!
