S'kay chaps, Eyetech have responded to an email I sent them and they said Hyperion reconmend ATI Radeon cards for best performance but my Vooddoo 4500 64mb AGP card is supported by both LinuxPPc and AmigaOS 4.0.
I knew there was a reason I liked dealing with Eyetech, the've never let me down in the past.
See ya - off to put all my games in ADF format ready for the second coming!
