Nvidia 9800 GTX no hardware acceleration in Mavericks

[Totaltimo]

Hello everybody,

I have an Intel DP55KG board and a Nvidia Geforce 9800 GTX+ (512 MB) card. Everything works fine, except for the card's hardware acceleration.
What I already tried:
- delete all NVidia kexts
- tried the Nvidia kexts from Dropbox (resulting in a black screen during boot up)
- tried various SMBIOS variations using Multibeast
- GraphicsEnabler=No and GraphicsEnabler=Yes
- deleted all ATI Kexts

Does anyone have another idea?

I am having the same issue with a 9800 as well. Have any solutions been found?
