Hi, AFAIK, Poser4 is uniprocessor only and makes no use of the features of any GFX card except as a simple display device. For Poser4 processor "speed" is all that counts, as well as RAM size, I think Poser may even have problems with advanced video cards, (driver conflicts) I've seen a few threads about it. Poser5 however threatens to change all that, including even gasp GFX card support, shaders, the works. Whether it'll see the light of day this side of Christmas is another matter... Athalons are both good and cheap, and unless they're running against code tweaked for the P4's new architecture beat it hands down in most "real world" tests. But I doubt you're buying a Dual Athalon just to run Poser, right? :) later jb
