AH! That makes sense. I just need a fast single CPU system I fugure the Intel 2.26ghz w/ 533fsb, 850e chipset, 512mb of pc600 rdram should do good for rotating Vina D, and rendering in Poser 5. Current system: XP home, a single PIII 933, intel D815 and 512mb pc133. Too slow for quality rendering in Poser 4 at any higher resolution than 72ppi with anti-aliasing on. And rotating Vina D, it "pops" from frame to frame, too slow. It's also too slow for my heavier Photoshop processing. Thank you very much for the in-depth typing. Any clearifications, please reply.
