Right, i plan to get a new MBP soon, but can't decide between the slower and faster 15". The CPU I'm not so bothered about, but I worry a bit about the lesser GFX ram in the slower one, as I'm driving an external 2560x1024 display in addition to the internal one. So, if can shed any light on this matter, having actual experience of MBPs and big displays lemme know. I typically have several many tabbed web browser windows open, several editors, maybe some video content playing, some PDFs in adobe, some text editors, mail, messenger etc. Lots of windows. (i tend to use virtue desktops also). If there wasn't much price difference, I'd get the fast one. But it's £200, and that would get me a lot of other kit...but then I don't want it to be running slow for everyday stuff. EDIT: Oh, and i'd have 2 gig RAM whatever, so RAM isnt' the issue running all the apps.
