Did u bother to open that review link??18% OC for 18% perf gain is a bit of a stretch isn't it? I know some other users tried to pass off 80% gains from 45% overclocks, but let's not get carried away.
At $350 it's a $50 difference, nothing has changed, a faster card is $50 more expensive and offers a richer feature set.
"Maximum stable clocks of our card are 1120 MHz core (18% overclock) and 1515 MHz Memory (26% overclock)."
"Actual 3D performance gained from overclocking is 18.6%." <- in bf3.
What's crazy is it even manage to match a 580 in BF3 of all games, with such a modest clock.
