The RX 460 should give you an at least 10 fps bump on 1080p Overwatch type games compared to the 750Ti. Though the 460 has 15 more watts of TDP.
Good job lad. Haha.
I found an AMD RX 560 benchmark at videocardbenchmark.net. Link: http://www.videocardbenchmark.net/video_lookup.php?gpu=Radeon+RX+560&id=3708...
