Hey
the article said gamecube is both digital and analog video output. If digital, it can do 480p @ 60hz...that\'s all. 480 seems a very good resolution. a medium quality, about 4 times higher resolution than N64.
But!...I think PS2 can go like 1280 x 1024p @ 60hz but dued to vram limitations and ps2 NTSC output, no games run any higher than 480p and some runs at a shame rate at 480i. It is possible to go higher than 480p even though there is limitation to vram?
Now to XBOX, why does people compare gamecube to ps2 and left out xbox? I know XBOX have both digital/analog video output too, what else? well XBOX have high quality mode like 480p, 720p, and highest 1080i.
