advanced warfare was a pretty bad pc port, it played choppy even on my i5 3570k and hd 7950....but on any actual good pc port you'd play stuff fine. Advanced warfare, due to so many problems at launch, also had its online population plummet pretty badly, even less people play it than mw3 on console. I'd get it cheap on console if you were really wanting AW. I had trouble ever even finding a match on pc
