I had overclocked a system with Core i7 860, 8GB RAM to, GTX570 .. My goal was to win with the installation 1-2 AA levels and to enjoy the highest degree of detail, Direct X11 and Physx games in general. The graphics card has more than erwartet.Im Tombraider Bench as the average frame rate rose from 60.7 to 95.3 FPS! Accordingly, I can gamble instead of FXAA loose 2x or even 4x SMAA. Tombraider, Crysis 3, Bioshock Infinite ..alles runs in the highest settings. The opinion of a computerized colleagues has confirmed. The processors of the jump brings not so much. I almost changed motherboard, processor, RAM and graphics card. This is absolutely not necessary, if one gambles on FULL HD. I am very pleased with the card and think that I am so for quite a while very well prepared.
Update 10/13/2013: I would also add that I am not a fan of noisy graphics cards completely. This card is quiet even under load to my mind. Incidentally, it does not take goers we pre-ago more electricity from the grid, at 50% more power - really good.
