Hi magoo,
seems that will pay me back the MSI board 650i. got all packed here w/ theirs RMA number.  sending tomorrow morning.

Running Sli now all the time (as in now!) no freezing no strange behaviors...but no extra speed too! ;(
Yes a technician changed the boards and installed all -  the guy did all -  except overclock.
He says is better to use like that and see. if is all fine, he'll overclok it for me.

Latest Bios for the Nviidia chipset, latest drivers direct from XFX site ( could get only after registering the product- very neat those guys!)
Still can't see any improvement that makes WOW..
I do have instaled sp2 in Poser 7. Marked 4 threads.
My last hope is the PoserPro 64 bits now in August they say...
Rest my case here.

I have spend way over my budget...and I'm not far from square 1 - when all that started - my 'need' of a new machine.
All new all shinning new drivers, bios..special technician etc...his opinion btw is: bet with you that the software is not ready for that.
When rendering the benchmark 's scene only active soft was Poser - then using about 25% CPU and 1,50 GB taking all 4 minutes. (http://www.renderosity.com/mod/forumpro/showthread.php?thread_id=2732765&page=1  )

Now, have you used special config. at Manage 3D  settings in Nvida CP?
If yes, whice ones? have you add Poser to it?

Well there's a smal detail here: I run Poser from external Western Digital 500Gb (7200rpm, 8MB) SATA but you see it's a USB connection to the pc.

Thanks for the support and smart advises about that board - yes you're right . Just the package itself makes you fall for it.... ;)   great product lay out and emballage, also seems to be a super good value. Not cheap, but probably worth it. let's see .. I'm stick to it for for the next 700 days ahead for sure!
See you around.....
I'm still crying for my mistake in buying that Sansumg 27" (model 27t) when the samsung HD lcd tv  37" is now for 25% less than the monitor and the 40" is also 20 less than the monitor 27"....well I have to live with one now...
See you around pal...thanks again.
Cris
