I have a geoforce 256 32mb card. Mike is correct about the power surge problems. Also, I found out the hard way that there are some real AGP driver issues with the Athlon 700 chip, the non Athlon boards, I currently have an Asus) using the new Via chipsets, and high-end video cards. Fortunately Asus posted some updated drivers for their card but I have had other minor problems in Win2000 not found in 98 (have a dual boot system - only way to go.) I could not even get my ATI all-in-wonder card to run properly. Except for more onboard ram, these cards do little or nothing to inprove performance in Poser that I can tell. As for your question. If I had only one choice, I would opt for 256 ram. Rob
