Ok, well as i said i havent checked the tests myself, only seen other people jumping up and down about it.
Personally i hope the new ones are good since intel has been slacking tha last few years and its never any good with monopolies.
Anyways, i hope poser 7 will utilise 64 bit and hopefully they will optimize the overall preformance, eating way to much memory imo.

If you want better renedering times i would suggest waiting for Intels Conroe CPU's, according to pre-release benchmarks they spank AMD in most tests, use less power and cost less.
I dont know how trust worthy these test are but i would not buy a new computer until conroe has been released since prices will most likely drop.
But maybee you dont want to invest in a completly new system.
