ATI HD4870 - Help?

[QetOnFire]

I've succesfully installed Mac OS X and it works.

When i was installing it, i used my old gpu. After i want to use my HD4870 gpu. i've been told that i could just install the drivers for my 4870 and then swap my cards.

But i cant figure out to install the driver for the card? Any help?

no driver needed if you are using recent chameleon & graphicsenabler = yes.
and a nice DSDT or flag in c.a.B.p if PCIrootUID is not 0 on your board. might be =1.
unless some weird version of 4870!
