Check out my sig and you will see my current Mac specs. Here is some important tips -

First, make sure to get a LOT of RAM. New versions of Poser and other software will take advantage of more than 4GB, especially since they are moving eventually to 64 bit versions.

Second, do NOT ever run a VM machine to run Windows programs with that are as intensive as 3D applications like Poser. They are best suited for basic use like word processors, a camera or remote control application or generic non intensive use.

Third, if you want to install Windows, do so via Boot Camp only so you can run native with no slow down at all. Since you are going with an iMac, you will have to put it on your single internal drive. If you had a Mac Pro, you can easily setup dedicated hard drives for each OS you want to boot to on startup. I have a dedicated drive for each OS of: Leopard, Snow Leopard and Windows 7.

Fourth, don't skimp on the video card either no matter what model you go with. Get the best one they offer if you are doing 3D.

Keep in mind there is NO difference as far as a Mac or PC is concerned in terms of file formats that are application specific such as Poser, Daz, etc. They are in a format designed to be opened by that program regardless of the OS you are running. I wish others in the market place here would understand this and not confuse people.

Good luck in your shopping.
