I quickly tried the demo and it appeared to show quite a noticeable speed improvement, so I jumped in and bought the whole package. I had the Pro+ version of the 6.x, and I went for the discounted upgrade to v7 of the standalone and plugin versions. These can be purchased separately or together, with the plugin suited to "as required" use from photoshop, while the stand alone is more useful for batch processing.
I had a poke through the options, and found it was using 4 CPUs by default. I'm on a Q6600 so I had up to 4 cores available. Definitely a noticeable improvement over the previous version! The option menu lets you run a benchmark on the various combinations of CPU cores and GPU for processing. This is what mine came out with:

Detecting the best combination of performance settings:
running the test data set on up to 4 CPU cores and on up to 1 GPU
CPU only (1 core): 1.36 MPix/sec
CPU only (2 cores): 2.8 MPix/sec
CPU only (3 cores): 4.41 MPix/sec
CPU only (4 cores): 4.37 MPix/sec
GPU only (GeForce GTS 450): 9.04 MPix/sec
CPU (1 core) and GPU (GeForce GTS 450): 9.05 MPix/sec
CPU (2 cores) and GPU (GeForce GTS 450): 10.7 MPix/sec
CPU (3 cores) and GPU (GeForce GTS 450): 12.2 MPix/sec
CPU (4 cores) and GPU (GeForce GTS 450): 10.5 MPix/sec
Best combination: CPU (3 cores) and GPU (GeForce GTS 450)
Interesting that 3 cores gave maximum throughput, with or without GPU chipping in. And there, the GPU gave a huge boost.
The interface has been boosted in display options now. I really need to do screenshots some time for this, as it will be a case of a picture being worth a thousand words. Suffice to say for now it gives some interesting rendering of noise components which may help tune noise filtering.
Will write more as I play with it.
