I got a cheap 7850 1gb msi card from ocuk for xmas(£125 bargain) and it works well,but im reading increasingly that with newer games 2gb of gddr5 is what is needed. my m/board is a gig z77 d3h which runs x fire at 16x/4x speed,would i see any big improvements xfiring,cant seem to find anythin on the net about this
