I'm looking at the 2.0 Ghz Macbook Pros and I need to make a decision. I want to use it to play games, but there is one problem: The graphic's card. Bottom line: how much faster is the 256MB ram version of the Radeon Mobility X800 then the 128 MB version. Should I try to find a store that still sells the old 2.0 Ghz Macbook Pros? Is it really worth the trouble, or should I just spring for the 2.16 Ghz model?
