Sparkle Calibre X580 Graphics Card Review

"  Sparkle has supplied us with a factory overclocked card at 810 MHz on the GPU core, 1620 MHz on the stream processors and 1008 MHz on the memory. The most obvious change from the stock reference cards is the addition of an Arctic Cooling Accelero XTREME Plus cooler. "
