Let's try to get this thread back on-topic, and correct some statements made in the thread. I can't comment on MAC vs PC because I've never owned a Mac (Macs are quite rare in the Netherlands) If you use a PC then either use a Windows2000 or WindowsXP flavour. Their memory management is much more robust then Win9x. Don't be tricked into buying an expensive videocard like a GF4 for Poser. They are only usefull if you play games. (And sometimes in 3DS Max but that is not what you asked about). Poser does not make use of any 3D acceleration features in those cards. Do not buy a dual processor system for Poser. Poser is a single threaded application and cannot make any use of the second processor. Rendertimes in Poser are only dependent on CPU speed and amount of RAM. Harddisk speed is not important, as long as you have enough ram so that you do not have to swap. (I bought 1GB DDR Ram for this reason) Your CPU speed can never be too much for Poser. Both a P4 and AMD XP will give you excellent performance, but if you want the fastest model the Intel processor will cost you much more than the fastest AMD XP model. I saw some comments about the heat the AMD XPs produce. If you have a good computer casing that won't give you any problems at all. Especially not with an XP which is already cooler then the older Athlon. I use a FK320 case (www.fkusa.com) with a simple/cheap coolermaster EP5-6I11 and the temperature of the CPU has never exceeded 40 degrees C.
