Have a 770 gtx 4gb card as extra for a pc when i get a 880 when it comes out. Need to know what people would use for a mobo and cpu. My second destop has a E8400, 6gb ram, and a gts 250. I dont have a problem with going amd for this build or a i5 4440. Have a decent case for it. Main PC is i5-4670k @4.2, 8gb 2133, 770gtx 4gb.
