So I'm a recent Mac convert, having bought my macbook back in December. Haven't looked back since. Anyways, I've recently sold my old PC laptop and PC desktop, and would like to purchase a new iMac. I was thinking the 20" base model for awhile, because the 24" screen is so large, but after playing with them in the apple store I'm starting to lean towards the 24" base model. I'm looking for opinions on which model to buy because besides the usual web surfing, music, videos, etc, I do some audio recording time to time. Also, is the graphics chip in both models sufficient enough to play the majority of MMOs? I don't play too many graphic intensive games like some of the first person shooters out there, but I have been known to play MMOs like LOTRO, WoW, etc. Thanks for the replies in advance!
