So I had a Powercolor 7870 XT and I RMA'd it. They've sent me 2 dud r9 270x's and I'm just tired of sitting around without a gaming capable device. What would be the best card for a 550w powersuply? Its a XFX Pro 550w. I've sen some GTX 760's and R9 280's that only require 500w (Link) But I've also thought about going big and getting a GTX 970 as they are power efficient. I don't want to spoil myself too bad though
