Hello, im building a windows 7 home premium 64bit pc just and only just for pc gameing, but mainly im just focused on grand theft auto 4. How ever, this is not my issue i need to know if a duel/quad core processor's will work. But im planing on getting a gts 450 for it. I have seen lots of youtube videos useing enb settings on gta 4 useing the duel/quad core processor's with the gts 450.
