Its GPU will be doing fine for quite a while. Halo 2 was prettier than Halo, was it not? And could a Geforce3 ever render Halo 2's graphics? Don't give me the 480i thing either because you could play it in HD resolution.
480P wasn't exactly HD either, considering a decent scaler will give about the same quality as long as it's a 30fps game. (which most of the better looking xbox games were)
And Geforce 3 played doom 3 better than the xbox version, and doom 3 could be considered better looking than halo 2. (and the xbox's gpu was closer to a geforce 4ti btw)
So far though, I've played several games on the xbox 360 and a PC with an x800xt, and the PC played all of them better than the 360. Maybe that will change as the Xbox 360 gets games that play to its strengths, rather than PC ports made for types of performance that the 360 is deficient in, since it does have a very non-PC architecture.
It was about the software, most of which never touched a PC.
That's right, it is about the software, and that's why the original Xbox was a waste of money its first few years and the 360 appears to be about the same...all their best games are PC games or multiplatform games that see release on the PC anyhow. Nearly anyone reading this forum probably already has a PC powerful enough to play the games at least as well as the 360, and many wouldn't be satisfied unless they had somthing much more powerful. Microsoft desperately needs to break away from the PC-lite mold if they want more than just people who are too cheap or not knowledgable/caring enough to build a good PC.
Oh, and sure you can play a 360 on a PC monitor, but that'd be like playing a PC on a TV. It's just not the most practical setup, console games are made with large text and icons so you can play them from a couch halfway across the room, PC games are made with small text and tons of detail because you're sitting about 6" away from the screen. (of course, now with more console crossover games, PC games are being designed with more viewable interfaces, some developers are actually getting quite good at simplifying interfaces will still keeping them fully functional, though there were some ugly attempts at the start with the original xbox)
