Thank's :) I have been reading reviews for over 10 hours by now and it still feel as i'm just scraping the surface. Here are a couple more in case anyone has some time to spare.. The first one might be hard;) As I'm not in a hurry to change the computer I suppose I could wait a month or two and get one of the nForce4 SLI cards. The question is, how do the cards work together. Say I get 2 6800GT 128Mb card, would they run as 2 GPUs sharing a total of 256Mb or will they load half the data each and work with there own part or will they have load all the data into both the cards and maybe render every second frame each.? Do i have to install 2 cards of exactly the same model and manufacturer(in case one starts with one card and it goes out of stock)?
