XFX 8800 GTS 320mb Fatal1ty Edition
Overclocking on the nVidia cards was performed using Rivatuner Release 2. Overclocking on the HD 2900 XT was performed using the AMD GPU Overclocking Tool.
A test run of 3DMark06 was performed after the overclock to verify stability and also if the OC was worth the time.
Note that no hard or soft mods were performed on the card apart from setting the higher clocks.
Here's what happened:
Note that the fan still hardly ramped up during overclocking (I didn't enable this feature in RivaTuner). With some aftermarket cooling like a water-block I think this card could push even more...of course this would void that rather nice XFX warranty!
