Im actually 5 boxing with an E6600 and only 3gigs of ram! long as i dont try to go through dalaran im fine. my vid card is a xfx 9800gtx. i use keyclone to set my fps to 30 for my main window and 15fps for my clones on low settings except a few things like distance and spell detail. still running windows xp pro. i have vista on a similiar machine and imo its the 2nd biggest pos OS from MS since ME.... guess thats why some pc shops are charging more to have xp installed on a new machine than vista
