Don't think I dont know that, but also consider that I overclocked the 9800 pro on the first 2 tests, and didn't on the 4.12's.
I also got 3...
4.12's are better
3DMark03 - 9800 pro
8.07 - 6004
4.11 - 6061
4.12 - 6074
Omega Beta 8.07 on 3dmark03 - 6004
Catalyst 4.11 on 3dmark03 - 6061
All tests were done with a 9800 pro 128 mb.
Will post 3dmark03 results w/betas and 4.11's.

I think any game can support AA and ASF, except maybe ones that don't use a 3d engine. (Starcraft)
Yes, enabling AA and ASF will decrease your scores by a lot.
It really doesn't make that much of a difference. Try searching the forums for some crazy german site that tested each setting.
