Hey there MR community! I currently play wow and am in a raiding guild. As of now I play on a old G4 tower case. I normally get 2-4 FPS when in fights during a raid and this can hinder my DPS by alot and even causes deaths! I am looking to purchase a new iMac when leopard comes out. Would a 20" iMac with 4GB of ram run well with all the addons I have running? (about 45MB worth of addons) Anything is appreciated!
