Dual Amd... sorry dude, i own a dual 2000+ machine and it rocks with maya! But 4 some reason, Poser is only able 2 use 1 cpu.. and seriously, 2000+ is much 2 slow 2 work whith p5.... (they'll implement it in one of the nex versions of poser) in my opinion, this is the worst lag of poser, because i have 2 work as fast as possible have a good machine 4 3d animating and poser can't use it ;[ but AMD ows anyway. U can buy a lot more power 4 ur money!!
