Summary: My profession is a software developer, but my passion is with technology and computers so I wanted to have my own dedicated server at home. I built a "server" before from spare desktop PC components but thought this time I should build one with actual server grade components. Since this is primarily just for myself, I couldn't justify the additional expense with Intel server CPUs. AMD offers great value for the price. This 8 core CPU is perfect for my needs.
Summary: I went with the Asus KMCA-D8 motherboard (which I don't necessarily recommend but I'll live with it) which fortunately came with the latest BIOS release already supporting the 4300/Seoul chips, so no problems there, just plug 'n' play. torsionbar mentioned there wasn't a great cooler selection but I beg to differ; sort of like his/her selection, I went with the Noctua, though I'm using the NH-U9DO (92mm instead of 120mm fans).
Pros: This is an extremely powerful little processor that runs very cool. It keeps up with modern desktop processors by being able to max out at 3.8GHz when running fewer cores. I grabbed two of these very recently to build a graphics workstation and replace a single older quad-core Intel Extreme processor and I'm shocked by the gains in performance I get with these, and how much lower temp they are because my system is darn near silent (see Other Thoughts below). I would h...
Cons: There really aren't any. It's just very well-priced for its feature set and capabilities.
Summary: If you are upgrading from a 4100 or 4200 series Opteron, your motherboard *will* need a BIOS update. Visit your mobo manufacturers web site and do the BIOS update *before* you attempt to install this chip! My Supermicro H8SCM needed BIOS upgrade to v3.0 in order to use this chip.
Pros: A fast chip with low power, perfect workstation or small server chip. A drop-in replacement for earlier 4200 or 4100 series Opterons, an easy upgrade!
Cons: None really. I wish AMD would publish a product roadmap, so we know what chips are coming up in the next few years.
Summary: I have 2 of these running in my server along side 8 hard drives and despite the 700W powersupplies that aren't even 80 plus, it currently only pulls about 300W running both CPUs @ 100%, plan to switch to 500W 80 plus plat power supplies which should shave off quite a bit.
Pros: 8 cores @ 3.1GHz
Cons: Not many great heatsink options for socket C32
