What is 1016 ? That is very low for your memory speed if thats what it is,,, You buy a 580 then you gonna feel bad when the 680 comes out and boasts twice the performance,, of your 450 dollar 580,,, You have a good card already,, to run BF3 at 1080p , 8xAA 16xAF ,,,,,,,,,, figure out whats wrong with it.. Maybe manually change the speed of the fan to 100 percent with riva tuner when you game,, then take it back down to 30 percent at desktop. Dont OC and use stock speeds, let us /me know.. thx, gl
