Ive done quite a few of these waiting to buy threads and i promise this will be the last on. Being a design student with the current CS4, my current mbp is starting to show its age and im looking to get into mobile gaming more as i do my design work. Ive decided to stay with apple and get a macbook. My question is, Is the 2.4Ghz model of the unibody macbook worth the extra $250 for me? or is the 2.0Ghz model sufficient for CS4 and take the extra money and up the ram? My main intention for this machine is to take the load of my 1st gen mbp with CS4 work and to make it my entertainment machine on the side. Only games i would play on it are WoW, CS:S, L4D, and possibly SC2 when it comes out. Like i said before, this is strictly for mobile gaming/entertainment and a extra computer for CS4. Thanks in advance guys!
