hi cant seem to find many comparable benches for gaming so does anyone know if I buy the 7950 what sort of extra performance I would see in games? for example in dirt showdown benchmark which I think is pretty intensive I get 82avg fps and minimum 60 on generic high settings. on ultra its unplayable dropping to below 20. so using that example or any other game or an ocuk members personal experience with either card is it a solid and genuine upgrade or should I look at another option for gpu
