MSI NX8600GTS OC Video Card Review
 

Clocking in at 700Mhz core and 1050Mhz memory, the NX8600GTS OC sports a 25/50Mhz increase over the standard nVidia reference set. The cooler is an upgraded design to MSI's "regular" NX8600GTS as well. When they're offering the OC version for the same price as the non-OC, who wouldn't go for that?"
