2.3 GHz Intel Core i5. 4GB DDR ram. I probably wont end up running anything on it because i don't wanna wear it out. I'm just curious. Graphics card is Intel HD graphics 3000 which i assume is somewhat decent. What do yah think?

Macbook Pro? You should be able to run just about anything, as long as the memory for doesn't eat up your RAM. Exceptionally large programs, like a video editor or Starcraft, may run sluggishly. Other than that, most programs should run just fine. If something you want to play requires more RAM, you can always purchase two 4GB RAM cards to replace the two 2GB RAM cards I'm assuming you have.

4 + 4 = Win

The problem for Macs is finding games to play. There's a larger market for Mac games on the West Coast, since Apple is located out there. For people like me on the East Coast, it may be better to install Windows Op Sys on your Mac, then run PC games. There's practically no loss in performance, and in some instances may run better.
