The wording of this makes me confused. When they say Half-Life2 optimised for Radeon 9800, to be bundled with ATi cards, do they mean the version you get with your ATI card will only work on an ATI card (similar to the way 3DFX used to bundle games that could only be played on 3DFX cards), or that Half-Life2 is being specifically coded to work better on ATI cards? I have a copy of Need for Speed 3 that will only work on the Voodoo3 3000 it came with. That doesn't mean that the full retail version wouldn't work on a non-3DFX card, just that the copy I had wouldn't.
