Umm.. basically you may have to do a complete overhaul and upgrade.
A Serial ATA drive is faster, so that speeds up teh system, more memory means better system repsonse, and a bigger video card improves the response to the notorious machine hog that is Poser.
That is, at least until it has an update to the program and needs more system resources.
Oh great.....that made a lot of sense. Like talking to my son Gary or the old one...Woliff. :(
