I mean, I have a PC with GTX 580. Not the fastest one maybe, but it fast enough to play almost every PC games in maximum setting. The point is, i don't see much difference between the best graphic on PC than on PS3/360.
So, if Sony/Microsoft double or triple the power of their next gen console (maybe using GTX 680/ATI 7970 level video card) I think the most beautiful game that they can create is the same as the most beatiful PC game right now, which is not much difference. No chance they can make huge difference like last gen (PS2 to PS3 or Xbox to 360).
What do you think?
BTW sorry for my english, i'm not native.
