you have a GTS250 I think so any idea how much FPS ur getting in GTA IV with highest settings at 1400 X 900. I did a benchie on my Q9550 with HD5750 and got 36FPS at highest details at 1400 x 900. If you can bench that (if u have GTA IV installed) do let me know, I wana see performance difference.
btw how much difference do u notice in games at stock vs OCed speed?
