Original drivers sucks, what drivers can I use?

[Amdk6II450]

The original drivers on the Asusv3800 cd are crap, for example if I look by information it says that I have 111(:confused instead of 32mb sdram,I can't choose any options because the pulldown menus aren't working and I only see a blue stripe.

And the Asus tweaking utility don't work.
I get an error with the following message:
This isn't the good videocard(Rivatnt 1/2/2m64/ultra or Gforce)

And the benchmark aren't good at all:
3d score is 44!!!(3dmark 99 max)
even my old videocard works better(Speedstar a70 sis6326 chipset score 400)

Does anyone know what drivers I should use?

BTW I am using the newest drivers from Asus(not the beta!)

goto www.nvidia.com and download the detonator 3.78 drivers.

No way... you should use 3.48 reference drivers Those latest video drivers suck *** For instance, I get 4 more FPS at Q2 (big deal? well, every small bit is nice though ) I get over 70FPS on AMD 450
so, that's cool
