It depends what you're looking for. If you need Poser Pro features and want 64 bit rendering, I would suggest waiting for Poser Pro 2010. Poser 7 Pro, even on a 64 bit system, isn't as fast in rendering as Poser 8, but Poser Pro 2010 should be a lot faster. But also a lot more expensive. If you don't need any of the extra features Poser Pro offers, I would really recommend Poser 8, not Poser Pro.

Quote - For big scenes P8 crashes all the time here. No problem with small scenes.
Poser Pro runs big scenes fine and I guess it because of the 64bit rendering engine.

I had problems running big scenes as well, but since I've switched off the library and switched to SreeD instead of OpenGL, my P8 runs pretty stable, even with huge scenes. Switching one or both of them back on, seems to make P8 extremely unstable on my system.
