is there an 'nvidia' wrapper that will allow the 'patched' (or unpatched depending on who youre asking

) dawn demo to be run on an actual nVidia card?
Is the whole deal with renaming the executable to quake3.exe a feature of the ATi wrapper, or will that work with standard nVidia exe as well?
If i buy a 5900U, I want to be able to do that!
Despite how much I love nVidia and always have, I am seriously considering ATi as a formidable opponent in the current gen of graphics accelerators.
I will wait until Doom3 then make my final decision most likely. My Ti4200 (@320/590) could probably support HL2 pretty decently, yes? Obviously without the advantages of DX9...
