What do you guys think of the motherboards that can fit two CPUs?

That will be my next board dual socket Server my opinion is this wait for DDR2 800 support for server platform :up:

They are the "cat's meow":D
Go follow Victor Wang's thread in the Intel section.
Just get out a drool bib so you don't short out your keyboard..;)
Well :)
I never jumped on socket 771 because of the FB-DIMM issue and the limit to 8 cores.
However, you can also get an 8-core Opteron socket 940 system reasonably cheap now. A couple 875s or so go cheap on ebay and the 4-socket boards went by for round $500 lately. Need a case for a 13x1" board, though.

I thought you had a dual socket 771 system? I must have misunderstood you.
The memory bandwidth issue isn't a problem in anything I use but you probably use apps that need it.
On the conputational side, I can just match a 16 core Opty 880 in cinebench with 1/2 the cores, a lot less elec use and less heat to deal with.
I'm not an Intel fanboy but I'm definately a fan of these systems.:D

They crunch well but the 4p crunch more :D

4P or 4 processor system crunches more than a 2P or 2 Processor system (assuming all other things being equal)

I have 771 Woodcrests at work, but don't own one.
With proper tuning of the kernel I got the runtime overhead of FB-DIMMs down to pretty much zero (the large cache helps a lot), so that's really not an issue. I just refuse to do a too frequent "buy all new" round like Intel seem to like to demand. The problems that FB-Dimms present for overclocking are more severe, and since I need 8 GB as a minimum I can't just cherry-pick 2x512 MB modules.
I am also not convinced that Intel won't go back to normal registered when they are able to have individual memory banks per processor.
