Ok I have upgraded a G4 gigabit  model with 2 gigs of ram and the Gigadesign 1.4 with L3 cache and have the 9800 pro in there.

Now, that said, I still want faster graphics IF I CAN GET IT.

I am willing to change out the logic board but do not know if the higher speed logic boards posts mystic will fit although I am willing to fabricate a solution.

I also realize if I go to a ddr lobo than I will sell my ram and get ddr.

I am running OSX and it runs great, but again I am after more graphics performance as I do not thing the 9800 is being used to its full potential.

Thanks for any suggestions or help
