Hi,

My current spec is as follows:

CPU: AMD Phenom II x4 955 BE
RAM: 2x2GB Corsair XMS DDR3 1600MHZ & 2x4GB Crucial Tactical Ballistix
MOBO: ASUS M4A87TD
GPU: Sapphire Radeon HD 7870 OC 2GB
PSU: SeaSonic S12G-550 550W

Now I am thinking about upgrading my CPU and motherboard and was wondering if you coulld answer some questions before I make any purchases.

1. Is the Xeon E5-2670 compatible with Asus P9X79 LE?
2. How do yu turbo boost this CPU from 2.6GHz to 3.3GHz and will it require any special kind of cooling?
3. Would I expect to see a large performance boost?
4. Should I get one of the motherboards that take 2 CPUs so I can add another CPU later?

Mainly using the PC for work, gaming and a little bit of photo & video editing but hope to do more editing in the near future.

Thanks

Yes it seems so, and I went down to ASUS and checked the P9X79 WS and it does list the original Xeon E5-2670 as a supported...

1. Surprisingly yes it is. It uses an LGA2011 socket which that board has (Common mistake is to try in an LGA2011v3, which it will not work in). However the board specifically supports the E5-2670v2. Make sure you are getting that processor. It is possible (likely) the standard 2670 will not work.
2. Its a Xeon processor, you cannot overclock it. It offers the Turbo boost feature (which is already on) to run 1-2 cores at 3.3 ghz in a burst need.
3. Yes this processor is significantly faster
4. The processor does support dual operation, however unless you are doing heavy multithreaded work (like 3d modeling and stuff like that) IMO it would not be worth it. Games don't use it. Video encoding may use it, but I just don't see that it would make enough of a difference to be worth the price of admission.

Just as an FYI these processors (E5-2670) flooded the market at a very cheap price because Facebook decommissioned a TON of servers with them in them. There are not a lot of non server motherboards that support it. In this case you need the v2 version, which is not nearly as cheap, but still a pretty good value. Keep in mind if you do go with one, they were running 24x7 for about 3-4 years. They are made for that don't get me wrong, but to some folks that may be concerning.

Thanks very much for the reply, that information was very helpful as I had assumed that because it was the same socket then it would have been fine (this is why I like asking before pulling the trigger).

I just checked the v2 prices and it alters things a little as it pushes things out of my budget.

I found this page which shows a list of motherboards for this CPU: http://www.cpu-upgrade.com/CPUs/Intel/Xeon/E5-2670_motherboards.html

Am I right in assuming that this list is for the standard Xeon E5-2670 (2.6GHz)? If so I will search for each board to see if I can find one in my price range.

Thanks

Yes it seems so, and I went down to ASUS and checked the P9X79 WS and it does list the original Xeon E5-2670 as a supported processor (and supports the V2 also):

http://www.asus.com/us/supportonly/P9X79%20WS/HelpDesk_CPU/

That reinforces that your original motherboard choice won't work but this will.

Your best bet is to double check the model before buying, just google it it will bring you to the support page for the board and then look for CPU support, to be sure.
