Unknown about the 6800 model since neither myself or any of my contacts have attempted to mod this model but the previous models worked fine both software modding with Riva Tuner in Windows and hardware modding for Linux systems. The GPU has been found to be identical to it's bigger brother in earlier releases so as long as you correctly mod your card you should experience the same results as if you had purchased a Quadro model. Hardware modding is not as easy as software modding but is an option for those with skilled hands. Considering though that not all manufacturers create identical cards even if the GPU is the same you should always do your research prior to modifying any hardware.
