it all depends on the what your hdtv can do. there is 780i, 780p, 1080i, and whatever else. i vs p means interlaced vs projected. projected gives off more vibrant colors. but, 1080 is a better resolution, offering something like 1900x1080, or something of the like. but yea, if your hdtv is only capable of 780's, then you get 1280x768, or whatever that one is. Kinda of funny, people that argue console are better say they are cheaper. but to really enjoy next gen consoles, you might have to spend 400+at least 3000 for a decent hi-def that exploits a next gen consoles full potential. screw that. i'd rather waste my money on a kick ass computer.
