Which 6 out of 8? In Clear Sky 295 is slightly ahead (not counting 2560 where the game apparently crashed), in Crysis it's slightly behind, in FC2 it's substantially ahead, L4D slightly behind, WiC REALLY ahead, HAWX REALLY behind, RE5 behind (at higher res), GTA4 equal. So --> pretty much equal even with AA. Without AA, it's faster.
And Nedjo, I don't think sending a Newegg link with the card $520 on it really establishes that the card sells for $520. Here's a Turkish site for you
