Just going to stop the argument right here guys... I'm not interested in dual video-cards for the moment anyway. As DV McKenna pointed out, a single card will do plenty if I get the 670, based on benchmarks I've checked. It's currently rated second (680 is first) in the high-end card benchmarks. If MWO will have any trouble running at max settings@1680x1050 on that, then PGI failed!
My max native monitor resolution is 1680x1050 right now (22" widescreen monitor) and I'm not planning on changing it any time soon, it's brand new and it's plenty enough for me.
but some day you will look forward to upgrade though?
