I've been thinking of an upgrade for a while now, and been wondering, if with my xfx 550w PSU I could power the new gtx 970, and would there be any bottlenecks to it if I were to use an i5-4670k with it. The rig is just a few months old so nothing wrong with that. Possibly just can get more out of my computer fairly soon so was just wondering if it was possible 😛
