So I need to get a new computer...

[Alowishus]

This probably won't be soon but I need to get a new desktop so I can actually play some games. I am currently living off my netbook (yes hilarious isn't it?) But I need a new desktop soon and all that so I was wondering what specs I need to run WoW and a few other high quality game like Diablo 3 and such. Thanks for any help!
