I've had this discussion before - and tested twice now P5 sr2 on a PIII 500mghz machine - 128 graphics card and 512 of ram. It doesn't work worth a s... In P5's defense and all 3d graphics programs in the forefront. They are more powerful and are made to work with the newer more powerful machines. Or so they claim. The more you want the 3d program to do the more it's going to require a bigger better machine. Especially for animation. Even the small new programs require more. For the price of about $250 and up you can get a half way decent mother board and processor between 1.6ghz and 2ghz. Personally I wouldn't recommend to any one that really wants to render - using P5 on a 500mhz machine and agree they should not be stating that as a minimium.
