Thanks for the reply fella's!
I guess the only good way to tell what it will do, is to just get in there and crank it up. I've got pretty good case cooling, so that should not be a concern. What's the best way to see if your card is stable at OC'd speeds? Should I just run 3DMark2001SE and see if it tears or locks up?
Is there anybody out there other than saturnotaku with an EVGA G4 that could let me know how theirs does?
