3D apps always use all cores. Modo, Maya, Realflow, and Houdini all use all of my cores.

that's not true.. 3d apps only use all cores when/if they have a render engine going..

for instance, autocad uses a single core for most (by far) of the workload.. when it does use all cores, it's actually mental ray which is using those cores and not base autocad..

sketchup has no render engine (per se) and it never runs on more than one core (in fact, it's still a 32bit app because there's no gains/need for 64 bit until rendering comes into play)
 
This is a good discussion because it addresses properly fitting the right machine for the right job.

Items like virtual OS software (Fusion and Parallels as example) would benefit from more cores so that they get more dedicated cores when being used without over taxing OSX at the same time.

As for other software, absolutely go to the makers site and find out how many cores can be used either by what they promote or forums if they have them.

What really is in question (for me and others) is Apple's use of a dual GPU and what benefits there are now. Unless Apple has a way to re-purpose the processing on these GPU's while one is being used (and the other available) there is for most software, no practical value. In the future, there may be with Open CL and such being more close to Intel, Apple and other's frameworks for tomorrow.

Maybe someone might want to start a forum on software that takes real advantage of 6 vs 4 (or more) and also the GPU set up on the new Mac Mini Pro.

exploits more than 4
Parallels
VMWare Fusion
etc.

exploits Dual GPU
Parallels - NO
VMware Fusion - NO
etc.
Just more peanuts from the gallery
 
I don't think the question is "which apps use dual GPUs". The question should be "which apps use OpenCL". I fully expect that the dual GPU business will be taken care of at the driver/operating system level so apps will be able to take advantage of the OpenCL processing power seamlessly.

Here are some apps that support OpenCL now:
Code:
Panorama Maker Pro 6
Maya 2012
Media Impression 3.6HD
Mari
Webcam Companion
Vray
Scratch & Scratch Lab
Maya 2013 - Autodesk claims a 5-7x speedup with OpenCL

Yes, I am well aware of the fact that many of these apps are not for OS X

Many more will support it in the future. If not, then I shall eat my hat.

I'm sure my FCP X would love to run on 6 cores; and while not transcoding videos or convert raw files it would be perfect for folding :D
