ATI beat Nvidia to the multimonitor-gaming market, and now Nvidia is going full out at it all of the sudden.
Nvidia could have also done this for the 200 series cards, but they didn't. Only now that ATI did it, does Nvidia do it.
Seems kind of like the big brother, now that you are eating icecream, he wants to eat all the icecream thats left.
You shouldn't be angry for that. Nvidia and ATI has never been obligated to support multi-monitor gaming. Regardless of which solution you choose between Matrox, ATI and Nvidia, you gain more from wider hardware support. That Nvidia supports multimonitor gaming, instead of downplaying it because they don't have it, gives more incentive to developers to support it as well. The user base becomes much larger with Nvidia's offering.
I see it as a positive trend that vendors go in this direction! :twothumb
