Alright I'm building a computer for a guy and I need some suggestions on what to get. He has an old computer currently but wants me to build him a better one for gaming. He primarily plays Everquest but wants to be able to play some of the newer games such as Bioshock. His budget is around $400-500. Considering it is extremely hard to build a computer for that amount of money I would say that he could use some of his parts off his old computer to save on some money. I think that his case, HDD, and DVD drive are re-usable. I compiled a list of parts but I am in need of some more suggestions that would give me the best bang for the buck. Thanks in advance for your help and suggestions.
