Besides Resolution there are still differences between TVs, and Monitors. TVs commonly do signal processing on incoming signals. They do this to Upscale, Downscale, Overlay TV user interface, Or otherwise adapt the input signal to the TVs unique qualities. Monitor's tend to do much less signal processing thus allowing for much faster input latency. Both Monitors, And TVs do this. TVs more commonly introduce input latency. That said there are TVs out there that allow for custom modes (IE Game Mode) of operation that can cut down on that significantly. As for performance of the card pushing either a TV or Monitor. There should be no difference Resolution for equal resolution on either. Again with the exception of Input latency being the real concern. Just make sure any tv you use has either a reasonable input latency out of the box, or can be configured to do so.
