I thought as such. This is the reason why I normally only stick with Intel chipsets. This via board still performs well with the games I've tried so far (Unreal 1+2, Unreal Tournament, Quake 3, NFS 3+4 as well as others) but it just doesn't compare to what can be achieved with an Intel chipset. I suppose I should be happy as it's been quite stable so far..."touch wood".

of course, older drivers would only support older cards released before them. the 4800 is released much later than 4600, i remember that all pre-40 drivers don't support any cards newer than 4600

Agreed. The 4600 was released on February 6, 2002 while the 4800 was released on January 20, 2003.
I suppose it might be possible to modify the .inf-File of the driver to make it detect the 4800, assuming there is no real difference, just a new PCI device ID.
