Hi all! May I ask you technical consultation, please? I have a Cube, and I'm looking for upgrade graphics card. GeForce 3 ADC for CUBE is still expensive on eBay. Apple begins sale Radeon X850 XT: http://topmac.blogspot.com/2005/06/radeon-x850-xt-available-for-power.html Will it work in the Cube? Yes/No -- why, how, ext. Comment, please. Thanks!
