If your tv has DVI, you can get just about any new nvidia card and hook it up and get full 1080p, its really not that big of a resolution to computers.
It's 1920 by 1080, so yes, it is that big of a resolution "to computers". If the idea is to play games at that resolution, no, most new video cards won't provide adequate frame rates. If the idea is to watch video, a $60 card with hardware acceleration would be fine.
