High Definition Gaming - Best Resolution?

With all the talk of HDTV and the next round of upcoming consoles, one has to wonder what the best resolution for gaming is.

HDBeat.com has a great article up about the different resolutions and what it means for gamers.

They state that higher resolutions such as 1080i and 1080p only run in 30 framer-per-second while 720p and 480p both run in 60 frames-per-second. 30 frames a second is just fine for movies, but as gamers we usually require the fastest possible systems for our action and twitch-based games.

The article also calls into question the PS3's required HDMI connection, pointing out that even TV's manufactured by Sony often don't support 1080P. With Sony's track record of over-promising and under delivering and the confusion of resolutions and formats, the article remains skeptical until Sony can show off the goods. Even then, what good is 1080P gaming if it is twice as jerky as 720P or even 480P?

What do you have or plan on getting for your gaming setup? Is HDTV worth it at this point in the game before we know about all 3 consoles and their capabilities?
