I built a AMD FX8320. I'm not a gamer but want to edit audio and some video. I was thinking of running R7 250 or 260 with 2gb of DDR5 for about $100 or more. I can get a GTX 650 with 2gb of DDR5 for around $68. Is it really going to be a big difference for what I do even though I've always been a AMD/ATI fan?
