Hello, Not new to Mac but not all familiar with the inner workings of these delightful machines. I recently picked up a nasty WOW (world of warcraft) habit and finding the lag a bit unsettling. I have an iMac G5 (no intel processor) and get some lag when i'm in some of the more detailed environments. I have upgraded my memory stick to...I want to say 1gb from 512 (not sure there) and I just bought another stick hoping that it helps the lag caused by the game. Buying the first stick seemed to help the first time so i'd thought I would try the repeat approach. Anything else I can do to make my machine go faster? Am I going the wrong way here? Please techs use small words and speak slowly. -MD "The scariest thing in my opinion, a rogue nature chimp after your banana."
