Dual 1366 Motherboard w/ overclocking?

[imrazor]

I've recently come into possession of two Xeon X5670s (LGA 1366 Westmere CPUs.) I've heard that they're really good overclockers, but I don't have a LGA1366 motherboard that will OC. Are there any dual socket LGA1366 boards out there that will overclock? Something that will take ECC memory would be nice too, but that may be asking too much...

I highly doubt that building a system based around these makes sense.

They are not good gaming CPU's, and there may be better choices depending on what SOFTWARE you used that have higher performance per core with less cores.

Add up the extra cost of system memory and a good motherboard for dual socket and I highly doubt this makes sense.

*plus, I don't think you can buy a new board and used boards may be crazy expensive or not exist.

I just checked and PASSMARK (which is roughly accurate but not perfect) shows roughly 2x the performance at stock for an i7-8700K.

Thus to MATCH the i7-8700K at stock you'd need to use 100% of all 24 threads in the Xeon system.

In reality MANY programs will be more than 2x the performance on an i7-8700K. Depending on the application's threading even some pretty inexpensive systems will match or beat these Xeons.

You'll also have potential compatibility issues with older hardware and difficulty replacing the motherboard later (even if you can still find one).

This video is a gaming comparison between an overclocked X5650 @4GHz vs. a stock i7-5820k. It actually holds up quite well...

Another factor to consider is that DDR3 is cheaper than DDR4. Just not sure which mobo to use, or if a dual socket board is out there...

EDIT: You're assuming an i7-8700k is within my budget. It's not, especially with RAM prices in the equation. And I have a good bit of DDR3 laying around.

EVGA Classified SR2. Not cheap.

Or this. Cheap thrills.

This may be relevant also. Not dual CPU YET, but maybe worth a try. Needs unlocked CPUs though.
