I have a new dual athlon 2400 (2x 2.0 ghz), my old sys was a 650 mhz pavilion. In poser, render times aren't all that different... The new comp. calculates shadow maps in a snap however, so if you're used to GI, then your times increase dramatically. But, the actual render itself is only about a 50% increase over the old pavilion... Evo
