nVidia Geforce 6800 to 6800Ultra mod
 

Very detailed guide at http://www.pcunleash.com/bbs/zboard....emReview&no=39


I have to admit that a fairly long period of time has passed between the day I came out with my notorious X800 mod, and today, when I am able to share my long-awaited 6800mod. One of the reasons it’s taken so long is that it took me a while to perform the necessary research for something as ambitious as the 6800mod. To be honest, I had had the idea of modding the 6800, even while I was publishing the X800pro mod. However, I didn’t have the entire 6800 series at my disposal at the time, so I could not yet verify if such a mod was actually going to work.

Lazyman beat you to it by no less then a day :)
