Who has Nvidia GeForce GTS 250?

I bought Nvidia GeForce GTS 250 recently as a replacement for my 8800GT. Anybody here uses the former and having problems? Quick let me know while I can still replace it. hehehe. .. =D

I just bought this one without really looking it up since I was in immediate need of a new video card, being my 8800GT won't run anymore. The 9xxx series seems almost the same to 8800 and some even have lower specs.
