TChittenden II
The firmware update appears to improve efficiency and performance. Why would you NOT want that?
The way I see it, there is no need for more performance as all the latest games play at 60 FPS. Skyrim. BF3.
Rage. Metro 2033. All the Mass Effect and fear games.
Efficiency seems perfect. It uses less power than my old cards. And as far as heat goes, most of the games run from 40 to 70 degrees centigrade. It will be even better once I water cool it.
