I've always been a gamer but have never had a system powerful enough to run even older games at high or ultra high settings and I finally decided to spring for a new desktop. I have been looking into parts but everywhere I look different components are discussed. Some people like the AMD Phenom sic core and quadcore processors and others say get a sandy bridge. Cananyone post a build in the $800 range (I can spend a bit more if necessary) and tell me why they would get those parts? Include everything from cases to how much RAM I would need if you can. I want something that will run pretty much any game on high settings without any problems. Thanks!!
