udgang, I STRONGLY recommend B, based on evidence, but here is an important question: does that AMD have 1024 L2 Cache? If it only has 512K that is a negative...from recent threads here, that L2 cache is really important. Your HD setup is important too, more important than you think, because Poser goes out to the page file a lot, even if you have a lot of RAM. Video card is NOT a factor in Poser 5 or lower, but makes a difference in 'working mode' (not in render speed) in Poser6 ::::: Opera :::::
