Re: anyone play on a macbook pro, newer?? I have a late 2011 17' SB macbook pro with a 6770M --- used primarily for Final Cut Pro.
All of my games are playable on medium-high (at least 30 fps) settings
The 650M is slightly better. Don't buy a mac for gaming --- there are cheaper solutions that are faster on a PC. If you have to have a mac for another reason and it will 'occasionally' be used for gaming -- then go for the 650M but realize you'll have to spent $1800 for it --- when better PC solutions exist for $1200
