Hi all. Right now I have an old early 2008 non-unibody 15" MBP. It's got a 2.4 GHz Intel Core 2 Duo with 3MB L2 Cache and only 2GB memory. I know this sucks compared to today's standards but, it does what I need it to. I use it for quite a number of things (though usually only two or three at a time), including email, internet, word processing (as well as excel, powerpoint, etc.), recording music with GarageBand, some video editing/exporting, iPhone app development, the occasional Mac game, and the occasional (lightweight) Windows game using wine. It does get kind of slow at some points, requiring a reboot to get going again, but actually less than I would imagine. Unfortunately, it's taken some abuse due to lugging it around in college, and I think it's time to buy a new one. I'm hoping to get the $100 app store gift card offer. There are two options for me. I want the 15" screen. So, assuming I get the 500GB 7200rpm hard drive and the antiglare screen, for roughly the same overall price I could get either the 2.0Ghz model with 8gb of memory, or the 2.2Ghz model with 4GB of memory. Or, I could get the 2.0Ghz model with 4GB of memory, and save $180. So, which is more worth it, the extra 200Mhz of processing speed or the extra 4GB of memory? Or, based on my current computer's stats, do you think I could get by with just 4GB and 2.0Ghz? (keep in mind though, I'm hoping for something that'll be overall "faster" [or less slow] than my current MBP) Any recommendations?
