Sorry, should have been a bit clearer, its not a performance issue - its the heat produced. I live in the desert, and even with ac running, they run hot and generate a lot of heat - so a more pertinent question would probably be, which cards run cooler, with comparable/better performance?
And Gyrene, I like the way you think fella - bigger monitor might work out, or I might buy another 23" like I have - amazing how much easier it is with 2 monitors work wise. Game wise, dont want to go down the 3 monitor route as yet, space on desk limited.
