Graphic artifacts in SC2

I started getting some of these today, not very often and only in Starcraft 2 (at least for now). I had the exact same type of artifacts in Warcraft 3 a few years ago and had to RMA my graphics card (was a Radeon 7500LE at the time).

Now I'd assume its the same issue but I'm playing on lowest settings with a 7month old Radeon 6870 that works at normal temperature and minimal load. (The reason I'm playing on low settings is because I still haven't upgraded my CPU).

So anyway if anyone has experienced something like this, have you found the issue to lie elsewhere than the GPU RAM?

Edit: Just to clarify the artifacts spike for less than a second and generally employ geometric shapes ;d

Heat. Load it with furmark and monitor temps. And maybe try searching.

I did search but most of the stuff I found seemed different from this (SCV lightshow etc). My main concern was that my GPU temp was 45-50C during this at 5-10% load. Ill try furmark and see if i get the same issue there, if I do I guess its a video ram issue and ill send it for RMA.

Or it could be a cooling issue combined with PEBKAC, which is why I suggested monitoring temps while it's under load. RMA won't fix that.

Here is what I got, I ran a 720 preset and a 4x AA burn in for 5mins, I think it looks quite normal, at least considering the settings i run SC2 in are the exact opposite of these. I'll drop this for now and see if i keep getting these still. If its possible for it to be a cpu issue, then it most likely is.

Heat is your most likely issue. Your airflow and/or ambient temps probably suck. Are you running at a framerate cap or with vsync in SC2?

Those temps aren't quite critical, but they're high enough to cause this sort of trouble.

It could be ambient temp. I got vsync in SC2, but it plays at below 60fps anyway, as for the temp, it goes high in furmark, but while playing it stays at 40-45 degrees. Anyway ill see how it goes and I'll clean the case of any dust, and hope it improves a bit.

You've tried uninstalling drivers in safe mode and reinstalling drivers, yes?

These kind of graphic errors (OP) indicate a dying graphic card. Might still be okay/fixable, if the problem is heat. If not, it's very likely already a permanent hardware damage.
