2011 vs 2012 Macbook Pro
Hi I am looking to buy a refurbished Macbook Pro. I'm in college and do graphic design work, photography and some video work. I also need a computer that can run The Sims 3. I'm trying to decide to either buy the 2011 version or a 2012 version. The 2011 macbook available specs:
15.4-inch (diagonal) LED-backlit Hi-Res antiglare widescreen display, 1680-by-1050 resolution

4GB (2 x 2GB) of 1333MHz DDR3 SDRAM
750GB Serial ATA @ 5400 rpm
8x double-layer SuperDrive (DVD±R DL/DVD±RW/CD-RW)
Intel HD Graphics 3000 and AMD Radeon HD 6770M
I'm concerned whether there are significant performance difference between the 2011 and 2012 versions. Especially with the graphics card.
