Agreed Cainam.
SilverTrine, not for nothing, but performance in one game shouldn't be a deal sealer for anyone with a properly functioning mind. I could sit here and say the same thing for Doom 3 and Nvidia, but not only think do I think it is ridiclous, but utterly fanboy like. Who cares only about one game when dropping 400-500 dollars on a hardware upgrade? Only fanboys if that is going to support their weightless arguments in all honesty. (not saying all debates are weightless, but when you use only one example, it obviously becomes a pretty shallow debate)
You would only be fooling yourself if you think that purchases are swayed by one single title, considering that HL2 really isn't that revolutionary at all. It's a good looking game, but doesn't rip any technological envelopes open in any respect. And visually, STALKER is going to kill it. And then, anyone with half a brain can look at the partnership between ATi and Valve and EXPECT the game to run better on ATi hardware sinced it is being developed in conjuction between both companies. However, early tests do not indicate this at all. There is no big lead ever or in any resolution from the R420 to the NV40 in HL2 right now, so what is your point?
If you think the differences in performance is going to be astronomical, you're not getting many others here to buy into it. Maybe if it was NV3x against the R420, many more would agree with you, including me. But this is a whole new ballgame, and if you choose to look past it like it doesn't exist, than that's your own weakness.
Downplaying SM/PS 3.0 is also moot, considering all ATi fanboys will rave about it once ATi implements it in future hardware. And that in itself is known as blatant 'hypocrisy'. Sure it may not make a big difference or have a total edge today, but it WILL matter in time. The differences could be subtle, or they could be humungous. Trying to downplay the technology and what it may bring us in the near future is ridiculous to say the least.
