I figure Poser will be my most computer draining software. I would like suggestions about system configuration (but let's not get really crazy - I need enough $$ left over to buy Poser 6). Athlon vs Pentium 4? 1 gig RAM or 2 gig RAM? Is there much difference? 128 Video Card vs 256 Video Card? SLI with double video cards linked via dual slots? AGP vs PCI express? I greatly appreciate evryone's input.
