Hi, I'm buying a MacBook Pro off of craigslist, and I found two that I found reasonable: 1. This first one was for $850 and had had it's hard drive just recently replaced: MacBook Pro 7,1 Processor Name: Intel Core 2 Duo Processor Speed: 2.66 GHz Total Number Of Cores: 2 Video Card: GeForce 320M 320GB HHD 4GB RAM 2. This one was for $725, but did not list the hard drive size (is it the SSD part? I'm not sure... but I emailed asking him the size anyway).: Processor Speed: 2.26 GHz Processor Name: Intel Core 2 Duo 4GB DDR3 1067 MHz Memory Nvidia GeForce 9400M 256MB Graphics 64GB SSD -- OCZ Vertex2 Both are 13". Anyways, the only real difference i found between these two is the graphics card and the Processor Speed. Keep in mind I'll probably only be using the computer as a homework computer/browsing, but will be doing some casual gaming on it as well (like MineCraft). And video editing for school. So is the extra $150 worth it? Thanks in advance. EDIT: Well stupid me mixed up the prices, and now I've realized that computer 2 (the 64GB SSD) is actually $725. Whoops.
