here's what I've learned 1) 1.5 GIG Ram. You can get away with 1Gig if nec. However, anything over 1.5Gig and Poser says "You talkin' to me? You talkin' to me? I ain't listenin'" 2) AMD processor with 1024K L2Cache. This backside cache issue is KEY! Don't settle for 512K. If I were buying a Poser-oriented rig, I'd go for the AMD 64 4000,$363.99 at Tiger Direct. 3) Install several small HD and put the OS on one, the swapfile on another and your Runtime etc. on another. Store only your current project pz3s on it. All other pz3s and project stuff on external HD, which you then back up with either DVDs or another External, which you take offsite. That's my 2 cents. ::::: Opera ::::: P.S. WARNING: If by any chance of the gods Poser 7 were to come out soon and allow the app to address multi-Gigs of ram, dual processor/core support, then all advice above in part 1 and 2 is void.
