http://mapage.noos.fr/campahunta/software/Graphiccelerator.html ATI Accelerator is now known as Graphiccelerator and now Supports the 6800 Series card. I have succesfully Overclocked my 6800Gt to Ultra specifications. My Gt was Originally Clocked at 350Mhz Core and 500Mhz(1000Mhz) effective memory frequencies. I am now running the GT at Ultra Specs 400Mhz Core and 1100Mhz Memory Speed. Stable so far and I am seeing performance increases in most Graphics functions. The Following Benches were Done on My Dual 2.5Ghz PowerMac Doom III at 1680x1050 Ultra High Quality setting everything maxed and I mean everything!! except FSAA which is off, I get 45FPS vs 42.2 FPS before OC. Quake III I now get 441 FPS at 1680x1050 Max settings vs 429FPS before the OC. Unreal 2004 AVG FPS now at 67FPS at 1680x1050 Maximum settings vs 63.9FPS. I used SantaDucks Bridge of Fate Botmatch bench for this. Serene Screens Marine Aquarium now tops out @ 500FPS vs 485FPS I am Very Much tempted to Overclock to 6800 Ultra Extreme specs which would be 450Mhz Core 1100Mhz+ Memory. I will go up to 425/1100 and see how stable things are. I read that in the PC world there are some folks who can Overclock their GT's up to 450/1200 but damn do they have balls! I would try but I have know way of reading the temperature for my 6800 so I really don't know how hot things are getting.
