XFX 8800 Ultra "Extreme" 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 when I started tinkering with clock speeds...
Again, as previously stated in other reviews, the cooler hardly ramps up even during heavy overclocking which is always a good bonus.
