I know the 480 is faster. Thing i'm worried about is the quality of the HIS card, I read their components are lower quality than say MSI or Asus. I want to keep the card going for at least 2 to 3 years and then maybe just add another one i could buy used by that time. Thought I'd go with the 8gb version to be futureproof a bit too. Got the wrong HIS card though, the one I'm talking about is the nonturbo version with a slightly lower clock. So wouldn't the sensible thought be to go with the 470 from a trusted brand and OC it to match a stock 480?
