For some of us, P5 is remarkably slower in responding to mouse clicks, switching liubraries, etc. as compared to P4/PPP. Like pdxjims said, get more RAM. It makes a big difference. Get as much as you can. I have 1GB and I'm a happy camper. (I'd be happier with 2GB, but I'm a greedy, happy camper.) You don't need P5 for clothes modeling if you have PPP. The P5 material room nodes are nice (if ... ahem ... quirky) but it won't affect your ability to import and bone the clothing. You might want to look at getting P-Wizard by kattman. It has a utility that makes setting up joint parameters much easier. (steveshanks of Poserworld recommends it highly. I've used it a few times and it did work nicely for me, as well.) Cheers!
