Hi, im thinking of buying a 2.53Ghz 13 Inch Macbook Pro. Im going to be switching from a E7300 2.66ghz Core 2 Duo PC with 2gb of Ram and Windows Xp. I need something a bit faster then my current configuration and was wondering if the 2.53Ghz Macbook Pro with 4gb of Ram would do me justice. I will be using it mostly for music production, using Propellerhead Reason software, and of course internet use, and HD video. Would I get better performance Switching to the 2.53ghz Macbook Pro?
