Easy test: go to youtube, and watch things that are in 1080p HD. They play fine in a window (using about 70% CPU), but full-screened to 2560x1440 they play at about one or two frames per second. Non-HD content seems to be fine even full-screen. Either just because it's so much easier to do, or because some level of scaling is hw-accelerated. It may well be that I'm using chrome (and chrome seems to tend to use its own library versions), and firefox indeed seems to be a bit better. But by "a bit better" I mean closer to full frame rate in full-screen, but lots of tearing - and it was stil using 70% CPU when displaying in a window. So I think firefox is also still doing everything in software but may be better about using threads for it. My previous i5-670 which was inferior in almost every other way didn't have these problems.. It had the same 2560x1440 display.
