install without any issue . no driver issue in Windows or Linux -lrb- Ubuntu Oneiric with fglrx -rrb- . very quiet - can not hear it over ordinary fan noise . run fine without a high-wattage power supply . like most modern card , this be rather large , but not unusually so - there be no problem get it to fit . run like a 5770 , perhaps slightly faster ? since most game be track a older hardware spec , it run everything I have throw at it quite nicely . overall , a very mature and satisfactory product
