Hi, I assume (perhaps wrongly) that a single 6970 would be a more future safe option, as I could easily add another later, right? I was wondering though, which would give me the best performance at the moment for now, as they come in at about the same price. The same with a 580 or 560x2. I've read that there isn't a great deal of difference between the models, if that's true, I should opt for the one I can get the better price on?
Thanks for any help
