Depends on the type of games you play. I think he should at least have a quad-core though and at least 4GB of RAM.
Well I think the issue is that Asus had clocked them even higher than promised. If they lowered the speeds to what was being promised as stock for the TOP cards, them seem to perform fine. I agree though, it's less than ideal to have to lower clock speeds from the factory. I just got lucky with mine. The EVGA FTW was another card I was looking at....can't go wrong there.
