Do you need a fast computer to play World of Warcraft

you need a decent computer. personally i have 512 MB ram which is below the minimum recommended amount. i also have a 512mb video card. with these, i can play the game for the most part, but have trouble when it comes to really intense graphics and when i am around other players. it can get quite choppy even with really good computers when you go into the large cities or the 25man raids. from that i have gathered from others, you should have at least 1gig ram and a 1gig video card. you will also need a fairly large hard drive, over 60gig. right now my world of warcraft folder is sitting at like 15-17 gigs.
