it be only be five day since I install this , but man do it make a difference . the last card I run be a hd 5770 , so switch up to double the video memory and 256-bit architecture be a dream of sort . highly recommend download trixx to set custom fan speed and overclock if you be into that . I have not actually oced anything on the card yet , but it already chew up everything I throw at it without complaint . Crysis run at max setting , as do Dragon Age 2 and the Witcher 2 . have not try Crysis 2 with the Ultra Upgrade yet , but I imagine this beast would chew through it reasonably well also . basically , be you want a card that can stay cool while also tear the scream face off you game , this be it .
