i wasn't sure if i should use EVGA precision or riva tuner, so i picked evga precision for the sake of simplicity, and it also works my zotac gtx260 . either i got lucky or this software is not exclusive to evga cards only.

so i got lazy and ramped up my clocks to Otis11's max OC on his gtx260. i'm now crunching at 700/1507/40, fan on auto at 40% 60C for 24/7 load win7 64bit. so far, 2 WU's has been complete at these clocks and they are both vaid. i'll report back if i get any errors. thanks Otis11!
