I have a Dual 1.8 GHz processor G5 with the Nvidia GeForce FX 5200 AGP graphics card. I am planning on buying a 23" or 30" Apple cinema display and need to upgrade to a new graphics card. The 2 GHZ G5 computer used the ATI Radeon 9650 graphics card which I have been unable to find on E-Bay, etc. Apple was no help! Has any one used the Radeon 9600 pro PC & Mac AGP with this computer? Thanks, Jim.
