Yeah, the ti200 is a great OC performer. I have mine set to standard GF3 levels now (200/460), but it can hit 233/505 and still have no artifacts and stay stable. Once I go beyond 233, I get lockups, but it's fine there. I don't run it that fast, since my system can run every single game I own at full detail AND FSAA on, and still be smooth.
