Well... to keep things balanced here. I believe PJF said that MAX was not FULLY (Fully being the key word)supported. As steve said. MAX works with AMD's even though they say it doesn't. My point is. These guys are just trying to keep Darkness on a known good path. Not into the testing zone. Where things may or may not work. I myself have seen much more noticeable speed gains from upgrading to faster CPU's. Than by adding ram. But I work with relatively low end machines. So that may be a different story once you climb in to the 400+ mhz. processor range. ScottA
