Good -- A 1:4 : 1 ratio sounds closer to "real" to me than 12.5 : 1 did.

I do find it "interesting" that Badaboom (which exists simply to show off how awesome CUDA is) is showing a  5.6 : 1 increase in throughput -- it's almost like they hobbled (or intentionally didn't optimize) the CPU rendering to make the GPU rendering look better...nah, probably not. 

And it just goes to show:  Like LvR indicated, if your CPU was a hotrod i7 instead of that old (albeit overclocked) Q6600,  I'll bet you'd find your CUDA to non-CUDA times to be pretty darned similar...midrange i7s are showing to be better than 30% faster in render benchmarks as compared to older Core2Quads, with a 50% increase in speed not out of the question when using the right algorithms.  I'll bet that plugin application scales similarly.

Not that CUDA isn't a good thing, because it is (IMO).  It's just that Pinnacle has so many problems with Studio that concentrating on CUDA (which what, 90+% of their customers don't know a thing about and couldn't use anyway) at this point should probably take back-burner to just making the darned software work reliably.
