Hey guys, I recently updated to a gtx 570 and i'm loving it but i have a question. I run three monitors at 1080p (not surround just one main monitor and two for other stuff), one off of my 570, which is the one that i run games, movies and other gfx intensive applications on, and the others for background web browsing or word processing. I was wondering, would I see a performance increase in metro 2033 and batman arkham city by making my 520 a dedicated physX card? because when i run games i never have anything on the other screens anyways. any input greatly appreciated, thanks in advance!
