Hi, i'm looking for a good desktop computer but i need some suggestiosn so i can make up my mind. i've never built a computer before and i've no idea what's the right price for it. However, my friend said that a good gaming computer usually cost alot. Just to let you i know nothing about hardware except mouse and keyboard. I'm really stupid when it comes to hardware. Do you suggest me buying or building a computer? By the way, i bought a 64 bit version of Vista on February 2009 and now Windows 7 is coming so should i stick with vista or move on to seven?
