Wow! I would love to see its PPD/$ of CPU. Anyone have any F@H results with these things?

....Anyone have any F@H results with these things?

Yeah I Googled that and found some guy getting 14 minute checkpoints on a 1760 pointer (P2653). Ummmm, not impressive at all. My OC'd E6400 is running faster than that.

According to fahinfo.org, you can get around 255 PPD per gigahertz per core from the Phenom. That's 1020 PPD per gigahertz. In Europe, a locked Phenom costs around Euro 80 per Ghz. An unlocked phenom comes in around Euro 90 per Ghz at its nominal clock speed, but will probably (evidence, anyone?) OC to a much higher level.
Taking the lower number as a safe banker, you get 13 PPD per Euro.

By comparison, the best Core 2 Duo score is 325 PPD per Ghz. I cannot identify which CPU this was on, and the comparison I offer is based on the Conroe. Here we have 317 PPD per Ghz per core, or 634 PPD per Ghz. Prices in Europe vary from around Euro 40/Ghz at the 21x0 end of the scale, through to Euro 60/Ghz at the E6750 (which is cheaper than Aris' E6400). If you use the low end price, this gives you a nominal 16PPD per Euro; if you take the high end price, the answer is about 10 PPD per Euro.

Of Course we are ignoring overclockability. I have read about people clocking their 2160 to nearly 4Ghz (probably members of the loud pc review team), but I have as yet no anecdotal evidence on the AMD Quads.

...the E6750 (which is cheaper than Aris' E6400).....

Yes, I've seen that. It has a mutiplier of 7, like the E6300. I'm sure Intel is aware of people overclocking, and the multiplier appears to be a factor in the price. The only way to get this up to 3.5GHz is to set the FSB to 500, that's a bit of a stretch.

The limit is 8 - I am running my FSB at 400. Which is easy. I am waiting until my wife's 2160 is up and folding to see whether I can run the FSB at 3500/9. If I could do that in my head, I could have gone on working as a CPA ROFL.
