Quote - Hi!

 I recently built a new computer and I was hoping for a large render speed increase in Poser compared to my old computer. So far I've been disappointed.. especially since I've only installed Poser 2010 + SR1 on my new machine (after drivers/windows updates) and no other software. It can only go downhill from here. :(

 My new PC:

 Intel i5 750 (2.66 ghz and a turbo boost feature to go to 3.2 ghz, though i don't know if that kicks in during Poser rendering)
Radeon HD 5850
High performance DDR3 RAM, 8 gigs
Windows 7

Old PC:

Intel Core 2 Duo (2.4 ghz)
Nvidia 8800 GTS
4GB of DDR2 Ram
Windows XP

 I rendering a shot with just 1 V4 with textures/hair/no clothing and no props or background. On maximum settings (No IDL) at 650x490. My new PC takes about 3 minutes per frame, my old one 5-6 minutes.  Does this sound normal? Am I wrong in thinking I'd get better with a minimal scene?

 I might overclock my CPU to 3.6GHZ, but I don't know if that's the bottleneck? 

 Any replied would be appreciated, thanks!

srry, but your new system is 2core with multihreading ,not a quad core.
(at last that is what the official intel website says)
multithreading does not help you a lot if the 2 cores has a heavy duty rendering job from poser.
(both cpu's running 100% for the render)

2 cores = 2 threads, like other people said use 3-4 threads want bring you much i think.
(the rule : one thread per core) Search the forums for this, a loat of people tested that.

lol, 8 threads with a 2 core ?. do yourself the favour and messure rendering times
with the setting of 2 threads and 8 threads, use 3d3 renderfirefly - rendertime.

one more thing
render seperate process should be checked in general prefereces of poser.
so ffrender can use more maximum ram.

you main bottle neck  is still you processor.
the new one ist not a big improvement to your old one.
you could have a remarkable performance boost with the intel  flagship i7 processor.
(6 cores = 6 threads.)
your old :   core2    2 cores at 2.4 GHZ
yours:         i5 750  2 cores at 2.66 GHZ
flagship :   i7          6 cores at 4.2 GHZ

overclocking to 3.6 GHZ ,
yes try it out, will improve your renderspeed if your system runs stable with overclocking.

you have enough ram (8Gig).
Are you using W7 64 bit or the 32bit version. ?
(i guess its W7 64bit otherwise 8G of ram makes no sense)
Only if you use 64bit version of Windows 7 and the 64bit Version of pp2010 you wil get the maximum performance possibel with your new system. (FFRender and all binaries in 64bit)

the intel i7 is the maxium and very expensive on my opinion.
an alternative would be the amd black phenom quad core cpu (4 cores at 3.66 GHZ)
cost's a lot less then the intel i7.
This in combination with W7 64 ,pp2010 64 and 8G of ram runs nice
(i have such a system)
