Hi all,
I'm planning to build xeon based PC for render and gaming. I have 2 options
1-) E5-1660v3 O.C'ed to 4.5 ghz
2-) 2x E5-2670 base clock
Which one will be better for gaming and render
For render 2x xeon will be probably better but I am not sure for gaming. Can you help me thanks

Overclocking a 8C 16T E5 1660v3 to 4.5 GHz (stock 3.0 GHz) will produce heat in the order of 300W. You need a cooler that is up to the task.
Dual E5 2670s will need a dual socket motherboard, which is very expensive even when used. The 12C 24T E5 2670v3 at 2.3 GHz when is dual CPU configuration will be very powerful in productivity tasks that utilise many cores, leveraging the full power of all 48 Threads.

For gaming you need higher clocks as most games use 4 cores.

To summarise in a very rough and layman way,
E5-1660 v3 OC 4.50GHz (8C 16T total)
Gaming: 4.50*4= 18.00 eGHz (effective GHz, eGHz)
Workstation: 4.50*8= 36.00+ eGHz

2x E5-2670 v3 @2.30 GHz (24C 48T total)
Gaming: 2.30*4= 9.20 eGHz
Workstation: 2.30*22= 50.60+ eGHz

You...

used xeon processors can be found for very low price on ebay. So if you ignore money which one will be your choice?

You will get better gaming performance with the E5-1660, but better workstation performance with the 2x E5-2670. You have to make a decision to compromise. Do you need more workstation performance at the cost of gaming performance? If you want an all rounded system get the single CPU setup.

Hope this helps :)
