Guys,
Whats a good bump in MHz to make my 260 GTX get a little nicer? Yaddamean?

Thanks, 5.0

I can run mine at 680MHz without any issues, temps are still good and it performs flawless. Full load at 680MHz it runs in the low 60c range. When I reach 700MHz I will start to get small artifacts and the temp jumps into the mid 70c range.
