Since when has any OEM-level board been able to keep up with the latest gaming software?
Valve games have never required cutting edge. Half Life1 ran just fine on not only the Voodoo1, but on software rendering as well.
The HL2 engine looks great, but it mostly looks like lots of hi-res textures, geometry, great AI, and physics. It does not use unified lighting, and the shader effects are not DX9, but look like regular DX6 fixed function multitexture class effects, thus, it may run ok at low resolution on any system with a fast CPU, since the geometry, physics, and AI will be CPU dependent, and the shader effects will probably run on DX6, and the hi-res textures can always be scaled down to deal with vid-mem problems.
How many owners of P4 2Ghz+ equivalent machines will run out and buy a -$100 video card (probably too many)?
2Ghz machines are value machines today, under $399, so I see lots of reasons to target this class of machines. Vast majority of these machines either ship with integrated video, or MX class performance.
I mean, for crying out loud, the MX440 runs UT2003 at maximum detail on 800x600 at 100+fps, and 1024x768 @70+fps. I could certainly see HL2 running at 60fps at 640x480 on a low end card plus value CPU.
