The Asus EN9800GTX went straight up to 852MHz on the GPU core, 1250MHz on the memory and the shader clock topped at 2106MHz. Regardless of the utility used (Smart Doctor, Riva Tuner 2.08, Ntune), I achieved the same result. All of these results are significant gains over the stock speeds. An increase of 177MHz on the core equates to a 21% increase in core clockspeed. A 20% increase in shader clockspeed (442MHz), as well as a 12%, or 150MHz, increase on the memory is nothing to shake your head at either. The performance potential is huge with the 9800GTX series of cards. With increases in clockspeeds like this, the expectations are high, so let's see how well it performs.
