PNY XLR8 GeForce 8800 GTS 512MB PCIe 2.0 Graphics Card
Overclocking Results
Before we concluded our testing, we also spent some time overclocking the PNY GeForce 8800 GTS 512MB card using the GPU core and memory clock frequency sliders that become available within NVIDIA's Forceware drivers when nTune is installed.

To find the peak core and memory frequencies for the PNY 8800 GTS 512, we slowly raised their respective sliders until we begun to see visual artifacts on-screen while running a game or benchmark, or until our test system was no longer stable. In our testing with PNY's GTS 512, we never actually saw any artifacts in any of the games, but the engine would either quit and/or we would get an error message from Vista referencing the ForceWare drivers when we reached speeds of 805MHz for the core (650MHz default) and 2.2GHz for the memory over the original 1.94GHz.
PNY 8800 GTS 512 Overclock - GPU=805MHz, Memory=1096MHz (2.2GHz DDR)
PNY 8800 GTS 512 Overclock - GPU=805MHz, Memory=1096MHz (2.2GHz DDR)
With the extra 155MHz we added to the core speed on the PNY 8800 GTS 512, we expected to break the stalemate so far between the two GeForce 8800 cards. Re-running Half Life 2: Episode 2 and Enemy Territory: Quake Wars showed that the additional performance gained in both engines made the card about 8% faster than the stock 8800 GTX.
