Hey guys, I just bought my first mac and so far im loving it. However, I bought the 2.16ghz instead of the 2.33ghz with the better graphics card. I do like to game quite abit and I'm thinking I made a mistake. I bought mine on Saturday and I've been downloading and using this one, will they still let me return it if I upgrade? I could also just stick with this one and upgrade my RAM, but I need some advice. Thanks.
