You're only going to see an SLI benefit with FSX
when running extreme resolutions where I understand it helps alleviate some of the extra load of anti-aliasing so many pixels. I run FSX with 3 screens using a Matrox th2go and the difference for me is very noticeable between 1 card or 2 cards. However, if you are just running a single monitor with a standard resolution, I wouldn't bother. Some have even claimed that it makes things worse. Obviously other
games will benefit by SLI in that circumstance.[/quote]
Thanks for the info, that is very interesting. I have two screen but only run one at a time, Gonna look into this with a bigger lens.
