Michael,
I do believe the min req`d is pIII333, so that should be ok. More power is always better. I think I remember something about the Oxygen vid card not working well though, I`m not positive. How big are your cad files ??
Are you rendering them ? We have an under powered system (new on order) & I leave the rendering off with files 20meg or more.......
