Also, I should mention that there is a rumour that HL2 will not be available to new customers who purchase the cards. I think that they are taking the vouchers out of the boxes or something. It's just a rumour, and I can't remember where I heard it.
Wolfy - True, but HL2 was designed to be the big ATI game, just like Doom 3 is designed to be the big nVidia game. It's a long story, and they only reason HL2 isn't close to be released (it's still months away) is because someone stole some of the HL2 source code, and they wanted to rewrite it. Personally, I think that it was a publicity stunt, but that's neither here nor there as they say.
