After about 3 years of using a premade Alienware computer, I want to build my own gaming computer. The Alienware I have now is slow, laggy, cannot load games at 60 fps, and often can't even load a number of games that are in my Steam library without a couple of extra tries. Is there any advice anyone can give as to where I should start to build my gaming computer? Any place to check for prices of parts, quality, etc? Thanks in advance.
