I might be able to actually afford this card... wondering if it is good enough to get last light to ultra on 60 fps... lowest I can go with is maybe 50 fps. Also, my specs are 8 gb ram, 6 core 3.5 ghz amd processor, 760gm-p34(fx) mobo, and 1920 x 1080 asus 27'' monitor. Can these parts run with the 7970 on a 600W power supply? Thanks for the help. Btw, the power supply is a corsair cx600..
