I wouldn't return any piece of hardware based solely on how poorly it OCs, but that's just me. I've read that the AIW cards don't OC well in general, so even after a return, you may not get a better overclocker.
My aiw9800pro also go as far as your noob_123, you're not alone. But I prefer AIW over the regular right now because I'm saving it for my second rig. Plus like the idea of surfing the net and watch tv at the same time.
