For comparison's sake, I COULD throw in my Athlon 64 3000+ into the ring as well. Although I already KNOW that a single core K8 is a bottleneck to today's games.
Anyway, I'll let you guys know once I'm starting with the testing.
To make it "fair" you should disbale 2 of the cores (if you can with your board) and then run them clock for clock.
I personally only noticed a difference in games with my 720. Other than that it wasn't really any faster than the Opty. But of course benchmarks like cinebench also had a marked improvement, but even the 720 crawled at a snails pace compared to the i7. Not like it matters though since I only game and type papers.

I can say with utmost certainty that yes, it most definitely will be. You'll maybe
see a 1000 point improvement in 3dmark06, if that, when going from a single GPU to crossfire.
You really need a CPU ~3.5GHz to see the true potential of those cards in crossfire.
