So I bought a 15in early 2010 MBP for $580 with a 2.4 i5, 8 gb ram, 500gb 7200rpm drive, and the 256/256 embedded and dedicated nvidia graphics card setup. My intention was to replace my mid 2012 13in MBP, which I will describe in detail later. Anyways I have replaced the 15in with a 256 gb toshiba Q Pro ssd and the latest Yosemite. It looks great and performs great. Decided to do a geekbench and magic disk test was disappointed with both results. It's was 2000 points lower in the geek bench and 240/260 read/write speeds. My 2012 Mbp has a 256 gb 840 pro ssd and 16gb of ram, with the original 500gb drive in the optical bay drive. Since I was doing video and music editing on my 13in and wanted to give to my wife I didn't think I would take a drastic hit in the performance section based of the scores I just recently did. Anyways I have been doing research on the 2010 MBp models and Wikipedia says the 13 inch supports up to 16gb, while a few users back in the day tried and failed with numerous 2010 set ups. I'm trying to find if anyone today with a 2010mbp variant can run 16gb of ddr3 pc3-8500 1066mhz. So far I really like the 15in and with the new ssd and 8gb of ram it performs the same as my 13in. I'm just hoping it can run that extra 8 gigs, and gain a bit more performance. Otherwise I might just try a 12gb setup.
