I'd like to know how big these companies think the market is for things like this. Do they really believe there will be millions of PC people willing to spend hundreds on cards (s, because the single 6gb cards are not even common on the market yet) and will happily do so? And they are continously targeting for this now? Good luck.
I mean, people have been asking when the next big jump in graphical fidelity was gonna be, with a lot of people being very vocal about hating the fact that games were still being tailored to the last generation of graphics.
Well, here's the future. Get ready to pay.
