Looking for a new GPU and I've spotted a few go up for sale today. Basically I want something under £200 ideally that will play most games at 2560*1440, without max settings. I don't need everything maxed out and don't play lots of games (despite my Steam library being stupidly large - damn you Steam sales and Humble Bundles). So I just spotted a Sapphire RX 470 for £150 at Scan. As an 8GB 480 for £210. Would the 470 suffice for my needs? For reference I'm currently running a GTX 660. Any other suggestions?
