I only really have time to play BF4 at the moment, and the gfx card I have struggles a fair amount at high (EVGA GTX760 ACX 4GB), so I have to keep it at medium. I've been toying with the idea of getting a 390 8GB, as I can get one for a decent price and the benchmarks look good for 1920x1200. My question is, is there a cheaper card that can run BF4 at ultra and would sufficient for my 650W PSU?
