Wow, if it wasn't for the not-as-cheap motherboards and the lack of recent features meant to boost performance (like NUMA and APIC-V, though I can't say how effective those are in the real world), I'd probably go for it as well. 300+ USD for a new mobo - especially when my current setup doesn't have any noteworthy technical issues - starts making it a bit hard to justify, though. Tempting indeed.

Tobias has no reason not to go for that setup either, since he could just reuse his 16GBs of DDR3.

    I know Alex has recommended the E5 series processors/motherboards
    for the best compatibility. There are 2 versions of motherboards
    that support that right now. Socket R and Socket R3. Obviously E5
    series processors are not very affordable brand new; however, the
    market is currently flooded with server pulled E5-2670 CPUs. They
    can be easily found for $60 on ebay. These CPUs work on Socket R
    motherboards. Additionally, these motherboards will still support
    DDR3 memory which is cheaper to acquire than DDR4 as well.

    That's where I'd start if I was you. Obviously there could always
    be issues with 1 manufacturer to another, but hopefully that's a
    starting place.


Nice tip!  You're referring to Sandy-Bridge EP, right?

8-core, hmmm that's tempting.
