ok i wanna upgrade my gpu and my price range is 210$ whats the best gpu i can get and not to much bottleneck
cpu-amd x4 760k something that can let me play games 1080p at good frames
mobo-a78m-e35
gpu-r7 260x
psu-evga 500w 80+
well, if you could go up on your budget a little i would go with the r9 290x, or for a little cheaper the 290. But for that exact price go for the r9 280x or for even less the r9 280.
R9 280 and GTX 960 might give 50% boost only . But X4 760K will bottleneck them without overclocking . I think , save some extra money for CPU/mobo/GPU upgrade .
