So true Rayraz! I designed an animation on my old P3 550 desktop. 5 secs. long at 480x360 30 fps. I was animating several terrains to simulate the water in a river. Each frame took a half-hour to render. I rendered the same file on my P4 2.4 laptop and each frame took less than 5 mins Each machine had 256meg of ram. I imagine adding more ram would speed things up even more.
