I have my GeForce 6800 GT hooked up to my Samsung HLP5674W. The high end Nvidia cards all support HDTV directly over DVI or at least the proper resolution over VGA (which is what I currently use). Set up was as simple as setting my desktop to the 720p standard resolution and connecting th PC to the TV. Initially the imagine was underscanned slightly on the TV but after the autocorrect routine on the TV my desktop perfectly fit the screen. All in all, super easy, and amazing to the eye. I highly recommend NVidia cards and Samsung TVs although most of the inputs are dissapearing off the new generation of Samsung TVs.
