Hello, I would like to use one PC with ubuntu and 2 graphic cards with 2 outputs (total : 4 video outputs). I usually use a Mac. Can you give me a good harware configuation using Pd and GEM equivalent to a MacPro configuration (2 intel Quad-core 2,8 GHz and 2 ATI Radeon HD 2600 XT) ? Not too expensive please ! Thanx a lot. ++ Jack
