Should I OC? I do realize running a 9800gtx on a 24" moniter is pushing it, if not its just able to run games on it just breaking 30fps, so would OCing both my proc and gpu bring my 3dmark score anywhere closer to what others are getting?
OC the GPU through Precision.
XFX is a pretty decent card so I would move the core clock up 25 and make sure that the link button next to it is checked so the shader clock goes up with it.
Leave the memory clock alone.
That should boost your scores a bit.
You should be able to go higher than that just watch your temps.
Once you get it how you want you can check the apply at windows startup on the left.
