Hi everyone, Just saw a craigslist post for a 2010 Quad core 2.8 ghz MP for 800. It has all the default components but does have 16 gb 1066 mhz RAM upgraded. And the owner is selling it for 800$. I already have a 2012- non retina MBP that I use as a desktop, but I've wanted a MP for the longest time. What do you guys think? Is this a good deal? Should I bite or pass? Thanks!
