Current gpu amd 4670 512mb,considering either Asus 760 or equivilent 770 version. However here in rip off britain 770 costs almost 50% more for not a great deal more porformance in the majority of games. Game at 1080p, this is to go into an HTPC so really want to keep noise & heat to an absolute minimum, if possible silent or near as damit. So can anybody run some benchmarks comparing 770 against a 760 at Identical clocks ie run 770 underclocked same as 760 clocks & report temps fps etc. Not concerned about all out performance just do not want something that sounds like a friggin hairdryer,either card would be a large upgrade. Play mostly strategy games,old rpgs emulators etc. The problem is would also like to play skyrim, the witcher & the odd fps shooter at a decent framerate otherwise it would be easy to make a decision. Any opinions or recommendations wellcome.
