Upgrade Options for My MacBook Pro?
I have a MacBook Pro (13-inch, Mid 2009). I recently purchased a game and noticed it lags a lot. I was wondering what options there are for upgrading my mac. Can I upgrade processors, graphics cards, add more RAM? And if not, are there any other options to get my game to play properly without having to buy a new macbook? All comments are much appreciated
Mac OS X (10.7.2)
