I'm in the process of building a new computer and it looks like these two are pretty close to each other when you overclock them.
The 805 has an advantage in that it's dual-core. 3.6-3.8Ghz is about as fast as it gets with a big air cooling setup.
The 356 generates a *lot* less heat - and 4-5ghz seems doable(stock is 3.33Ghz!) with a good board. With its 512K L2 cache, it's comparable to a first generation Northwood/P4 from the tests that I've seen.(Mhz to Mhz it's about identical) A 5.0Ghz Northwood would have been quite an accomplishment - and still would do well today.
I've yet to see Tom's do a review of this processor, though. It seems like this might be the better option than the 805 as you don't hit the same power and thermal barriers as quickly. I hear that someone got theirs to nearly 6Ghz with water cooling, but that's a bit silly.
EDIT: Yes, everyone says that it's no good for gaming, but so far I've only heard opinions - no hard numbers.
