this Sapphire card is a damn good overclocker indeed, but the results (overclocked) with doom3/HL2/FarCry are not so different. I was expecting to see more fps, when 3dMark shows a 22% increase...
From what I understand by reading this review is that this happend because:
"In games however, this difference will not be noticed, as the 4 disabled pixel pipelines greatly affect performance for the settings we chose to use (4xAA and 8xAF)."
