If you upgrade it up to 4gb and set the framerate of the background windows low (5-10 fps) its doable but you won't want to enter shat with them all.

But yeah, you'll need something a bit more upgradeable to run 5 on the same machine. I'm considering a powermac just for this purpose as my poor imac is about to have a meltdown. If you are able to the suggestion for a windows box is a good one as well. I hear they run Excel really good too for those days you want to add some numbers together :thumbsup:
