Re: Doom 4 30FPS cap (?)
Two quick follow-up points...
I agree graphics matter, mostly for the sake of immersion. I don't think consoles suffer so greatly in thie regard as you postulate though. I know of only a few games that really suffer from tearing, and jaggies are not so bad when viewed from far away. If more games were like Crysis and fundementally better, as in better base assets, larger worlds, etc., then I would agree with you more... those days seemed to have passed though.
Secondly, my comments on Doom 4 and the consoles relate to PC in this way: the better console they use as a base, the better the PC version will look/play.
I gots one of them high powered gaming computers with an EVGA GTX 480 video thingy and a Q9550 processing device and also one of them Windows 7 64 operating programs with 4GB of some Corsair 1033 DDR2 ram.
