GPU will be roughly equivalent to a Radeon 7850. At 1080p, expect a lot of current gen games to be run at 60 fps at first, but next gen may be locked at 30 fps.
Those Killzone screenshots have some very nice AA going on, I doubt the 7850 would be running that at 1080p with a playable framerate. Plus the screenshots are in 2048x1152, probably running at 5 fps there on a PC
