Hi, I'm going to be quick and to the point here. I have a fx 4300, 4gb of ram, and a cx 430, and a micro atx case. I need a new gpu to upgrade from my gt 630. I was looking at the 7770 direct cu 2 2gb and the 7790 direct cu2 1gb. Also, the r7 260x 2gb xfx is also a choice. SUprisingly, the radeon 7790 is the cheapest, but is sold form a 3rd party seller used on amazon. I need some good suggestions for a good budget card. Thanks.
