I know this topic has been covered multiple times, but then the discussion was between the 2.4 and 2.54 UMBP models. Now, with the updated "high-end" stock config I am not sure which to buy, before I was leaning towards the 2.4 because I could not justify the price increase for the relatively small speed increase I would be getting. But now I am thinking that because I am going to replace my old 17 SR MBP, I might as well go for the higher end version. I will use this computer for some light gaming, photo editing, word processing, HD movie playback, and just typical web browsing. From what I have read I will not see a large increase based on the processor/cache and video ram but will these combined give me a noticeable speed increase? I am looking to keep this computer for 2+ years.
