The EVGA 6800GS CO Superclocked is the highest clocked 6800GS available on the market today with a clock speed of 490MHz for the core and 1.3GHz for the memory. The performance is higher than the standard 6800GS CO card which I've already reviewed on Motherboards.org and two of them in SLI mode are faster than a 7800GTX. The 6800GS CO retails for $269 with a $20 rebate. EVGA Support is second to none in the industry. The combination of the Step-Up program, 24/7 Live Toll-Free Telephone Technical Support and a Lifetime Warranty make this company the number one choice for those wanting no-holds barred support for their NVIDIA-based video card. - gamepyre.com
