I'm currently in the market for a new graphics card. I'm considering getting the factory overclock 1000mhz 7950 from gpushack for $129 or a used GTX 760 from a friend for $120. My psu is the Evga 500w 80 plus and I have a non overclock fx 6300 cpu. I'm more interested in getting the 7950 because it has 3gb of vram; however, I was checking their power consumption here. http://www.techspot.com/review/496-amd-radeon-7950/page9.html Is that the power consumption of the GPU only or whole system?
