Hi folks So I've got a 17" inch unibody, 320 7200 rpm 2.9ghz arriving on friday. With the advent of the new iMacs, I'm wondering if it is worth getting that instead. The 3.06ghz processor does not change much, and I have 4 x 1TB harddrives at home anyway, so that does not matter either. I hardly move my laptop, but am starting music uni in september and so may be doing so then. The biggest difference I can see is the Graphics card. Is the ATi 4850 miles miles better than the 9600m? I suppose it is..I game quite a lot, but even on my 2.66ghz x1600 256 mb, I'm playing fallout 3(lowest graphic settings but I can still really enjoy it). I supposing in terms of music recording, there will not be much difference in performance between the two? Any thoughts?
