GPU-related problem?

[Jonesiani]

Please move if in the wrong place.

Hi everyone, just got my new build up and running, Q6600 OC'd to 3.007GHZ, 4GB Geil memory, 8800GT, Gygabyte mobo, LG L1900R, Tagan 480W PSU

Basically, i've only installed all the drivers out of the box, so to speak, as my new rig isn't online yet.

Doom 3 - Spot on, everything maxed but x8AA

Dawn of War (with all expansions) - smooth for 5 seconds, stuttery for 5 seconds

Far Cry - All maxed, fine.

FEAR - All maxed, but no 1280 X 1024 res option?

Soldier of Fortune 2 - Fine for about 20 seconds, Big freezed for about 1 seconds, fine again.

Could this e a driver issue or something, temps seem fine.

Any opinions great, thanks!

It might only be 480W, but it's a rock solid PSU. Iv'e known people to power GTX cards of them. Still, worth thinking about.

On an update, Serious Sam 2nd Encounter is the worst of the lot, looks god, but stutters and pauses all over the place. Im thinking drivers.

I need to get this online.

Thanks!
