I've got a ATI RADEON 7500 32MB ADC VIDEO CARD N10476 in my 450 MHz Cube. It was easy to install all I had to do was swap the mounting "fence" from the stock card which required drilling a few holes. It's probably not up to gaming but seems to work fine for my pedestrian purposes. Supposedly it supports dual monitors, if I can get my hands on a DVI monitor I'm planning to try it out. Does anyone know if the cube will do display spanning (extended desktop) rather than display mirroring? Andrew in Ann Arbor
