Sapphire HD7950 Artifacts and flickering

[GoesLikeHell]

Hello

I've started using Sapphire HD7950 (950MhZ edition, 11196-10-40G) since wednesday. Everything has been ok to the point when i installed CoD Black Ops. I see artifacts, black shapes. Every other game (GTA EfLC, BFBC2 etc.) seems ok to me. It happens on stock speed(950MHz, 1250 MHz memory). I tried underclocking it but has the same effect, tried 12.8 and 12.9 beta driver, still the same. Would RMA be needed in this case or is it just faulty drivers? Temps are 50C-70C in gaming.
System specs:
Intel Core i5 2500K (stock)
Kingston 1600MHz 2x4GB RAM
OCZ StealthXStream2 700W
Sapphire HD7950 OC 950MHZ Dual-X
AsRock P67 PRO3(B3 Revision)

Any suggestions?

you aren't the only one having issues with that game (others with that card, other cards and even people on PS3). Look for patches for that game, otherwise go tell them in their bug report forum.

If the card runs well with other new-ish games, then it's fine. Temps you say are fine. Don't play with clock speeds as it's completely irrelevant and can burn it if you don't do it with skill.
