Quote -  OK , I hope to build a new animation set up based on Poser , what Mac computer would I  purchase to run fast and smooth rendering.
How many bit / memory / any ideas.
I am using Poser 8 Poser2010.
Thanks Guys

A couple of things to rember.  On the mac side of the house, only the renderer is 64-bit.  This means that while building a scene, you will be limited to 2GB per process.   Hopefully, the developers will get the code base moved to the 64-bit Cocoa libraries by the next iteration.

The renderer (FFRender) on the other hand seems to use as many cores and as much ram as you can throw at it.

The key is (as with all modern computing) Cores & Ram, Ram, and oh by the way, more Ram.

I will be replacing my 1st Gen Mac Pro with one of the new Mac Pros (12 core) for my birthday in Feb.   That is out of most peoples price range however ($5K or there abouts)  But 12 Cores (24 w/Hyperthreading), and up to 64GB of ram will future proof me.  (I work off a 5 year cycle)

If you can't afford a Mac Pro, I'd recommend the large iMac.  Just make sure you stuff as much ram in it as it will take.  1 caveat.  Don't buy ram from Apple. Get a reputable dealier on line and pay half of what apple charges.
