Don't let these guys scare you. Sure, a bigger more expensive computer will give you faster results, no doubt about that - but my fastest computer is a 2GHz cache-crippled Celeron with a 5400 rpm IDE drive and a cheap nVidia FX5200 card, and I can pose too ;) RAM is useful, though - my Poser 6 box says 256MB required, 512MB recommended - you want these 512MB, or more. And make sure you use Windows 2000 or XP.
