Hardware 2X Xeon E5 2640 v4 VS Xeon E5-2687W v4

What is your site?
Seems both are very powerful .

It's not over kill or over powered?

I'd choose this:

Which hosting is this by the way?

 

So this server:
https://www.ovh.com/us/dedicated-servers/infrastructure/1801eg05.xml

That is a beast.

 

Wow, that seems like a lot of horsepower, or your forum must be very busy!

I run a large XenForo forum (11.7 million posts, 1,000~2,000 users online, 1.4 million visits per month, 5.4 million pageviews per month) and WordPress site on a dedicated server at ReliableSite with the following specs. Using Centminmod, the site is blazing fast and there is very low server load with what seems to be plenty of capacity left over if needed.

Intel Xeon E3 1230 V3
32GB DDR3
2x 256GB SSD (RAID 1)
2x 1TB HDD (RAID 1)
CentOS 6.6

The server is two and a half years old.

 

og Google Analytics Real Time, how many online users?

 

Usually around 400-500. The server has handled spikes over 2,000 with no problem.

 

Of course.

I'm not an expert and I'm sure they could be further optimized, but this is what I have been running for some time now. I am running PHP 7.0.25 now.
