In my desktop I am currently using a Radeon HD 5770 (and don't have trouble running games on max setting & max res). I am wondering how much better this mobile gpu will be? The 5770 is quite old now, but one of the best 'cheap' cards around, and the 7970M isn't even out yet, but I am still wondering how it compares to desktop gpus, and more of how much of an improvement it would be to me.
