I'm currently a PC user but I love graphic design and have been wanting to switch to OS X since Leopard but haven't made the switch. After the recent update to the regular Macbooks I really want to switch since they're now brand new and have a pretty good grahics card. I was originally just going to save up for the $1300 version but now I am considering putting out an extra $300 for the better one but I don't know if it's worth it. So basically.. Is there really a big difference between the 2.0ghz cpu and the 2.4ghz? I don't really care about the extra 90GB because I'm going to get an external hard drive anyway but I don't know if the cpu speed is really worth $300. I am going to replace my PC because it is pretty hold and would like to play a few games, but mainly just WoW, but not really too many. Thanks.
