Hi, Going to university this coming September and i am thinking of replacing my ageing powermac g4 for a 13" macbook pro. the thing is i don't know whether to look at getting one now or waiting till they upgrade them? I know they're getting this sandy bridge thingy but from what i understand, that will mean going back to Intel integrated graphics? i don't really game that much, but i do occasionally dip in and out of WoW? So i guess my question is, what would be the CPU improvement if any? and what is going to happen in the graphics department, sticking with the nvidia or going back to Intel? and would Intel be worse or better than the existing graphics ? Thanks.
