I recently just OCed my NVidia GeForce Go 7900GTX from 500/600 to 600/750.
Everything runs fine, although I
DO get Artifacts in ATITool, but my games and everything runs fine.
The only problem is, when I try and open a Steam Game (DOD, CS, CSS, etc.), there's a scratchy blue/green screen that pops up before, and I have to ALT+TAB into Windows, and back into the Game.
After I do that, it's gone, and it runs flawlessly.
Is that really a problem? Should I downgrade the clock? I'm about to run some 3DMARK05 Tests on it to see what I get.
One more thing, my idle temps for my Dell XPS M1710 are 45/60 WITH the Overclock, on a wooden desk. I'm thinking of getting a Spire Pacific Breeze Laptop Cooler to help move the air around, and I'll be opening up my XPS (MAYBE!) to clean it out with some compressed air

. Also, I'm about to get a new desk, which is Glass, so hopefully my temperatures will drop!

I'll reply ASAP with my scores!
