600$ ??? Well, if I remember right, the 4870X2 was the same when was launched for the first time. In Japan was even more expensive like ~ 700$, so no surprises here. We cannot wait for review with the board O.C. !
Yeah, that's a bit steep of a price tag but I guess it is meant for enthusiasts only. I have my Radeon HD 5850 and can play any game out right now anyway.
