we all agree ram is the key to happiness. The debate is what offers the most ECC

DDR3-1333
like Lynnfield. To use Intel's 6 slots vs AMD 4 slots, one must use Registered
ECC.
So the low cost mission is something like
AMD Phenom II X4 955 Black Edition Deneb 3.2GHz Socket AM3 125W
$150 http://www.newegg.com/Product/Product.aspx?Item=N82E16819103808
$ 85 http://www.newegg.com/Product/Product.aspx?Item=N82E16813131609
$ 60 http://www.newegg.com/Product/Product.aspx?Item=N82E16820139050
But we are still stuck at 8G without going to expensive ram or
a more expensive CPU
Socket AM2/AM2+ supports a maximum of 4 DIMM sockets (2 dual banks). I
/think/ AM3 has the same limitation, but I can't verify that.
As for Intel, I can only find a single 6-DIMM motherboard for LGA1156
(the i3/i5/i7 socket, not the LGA1366 i7-only socket). It's $250
(http://www.newegg.com/Product/Product.aspx?Item=N82E16813128410)
Frankly, for more than 8GB, your best bet is to pick up an EOL'd
motherboard - a dual Socket F board which supports an AMD Barcelona-era
Opteron is probably the best buy - $250 for both, give or take. And,
Registered ECC DDR2-667 runs less than $50 per 2GB stick.

In reality, what I've found is often the best bet is to get an older IBM
system from eBay. There are plenty of them around, they're pretty
cheap, and parts are relatively inexpensive. For instance, I just got
a (new, still under warranty) IBM x3500 for about $500 - it's a tower
case. The 2U rackmount IBM x3655 is also a good fit here. The sole
drawback of these things is that they aren't exactly built to be
super-low power. Oh well. But they've got all sorts of nice bells and
whistles. :-)
(good news for me: I got fully-tricked out x3500 with 2 dual Xeon 5140,
8GB of RAM, 4x73 SAS and 4x750 SATA drives for under $1k. AND a
battery-backed raid controller. AND a real Service Processor. AND that
includes the 3-year IBM warranty. And, it runs OpenSolaris 2009.06 with
no tricks require - simply boot, install, and it's all set.)
