Did anybody do a testing between the two processors? Trying to figure out if the speed difference is noticeable. Or can you only get the higher GPU w/i7? I haven't checked MS website recently.. Mostly I do photo editing, web browsing. And on the side video playback (movies) and gaming. But since I have the SP2, gaming has been a letdown. So I haven't really played games much on my laptop, but I would like to when I get a chance again if I upgrade my SP2. Yes, I know we're talking about the SB2. But ATM, it's the only one with the better GPU.
