Hi..
I own an Eyefinity-System and I love playing games in huge resolutions (5780x1080). As a matter of fact, a game like Project Eterniy is not the typical type of game supporting huge resulitions because of the restrictions/size of maps/dungeons/whatever. Nonetheless a proper support of eyefinty(AMD)/Surround(Nvidia) with a centered UI and proper "zoom" would be a great plus to the game.
Maybe it would be possible to use the both side monitors for maps/inventory etc.
