Nowadays yes. With several cards shipping with 3xdvi ports as well, it often times is even easier to connect 3 monitors using Nvidia than AMD since you have to fuss around with active display port adapters (assuming you don't have display port monitors).
Yeah I was thinking about media centers today and how well a card hooked up to a TV and monitor would fare for movies and such. Thus I got curious about why everyone says you are limited to ATI for multiple monitor setups and decided to ask the question. Thanks for the replies.
