Has anyone tried a dual E5-2670 build for MB purposes? They are 8-core 2.6/3.3 GHZ turbo Xeon. They are being unloaded on ebay for less than $70.00 per chip. The real bummer is the motherboard, all of the less expensive ones have been snatched up so now you're looking at $350 for a new one.

Seems an ideal setup for a mass multibox on 1 PC for some more CPU intensive games. Before I jump in I figured I would see if anyone else has tried this.

this has been discussed before, tho I can not find the link,
any way the short answer is
Games do not use the 2nd /+ cpu/s , it would be a complete waste of your money.
The software has to be written to use multiple cpus in parallel and no game as far as I know has be written.

Thank you but I am talking about multiboxing here. Running 6-10 instances pinned to individual cores.

You're assuming he's wrong in remembering that games won't even recognize n+1 physical CPUs versus n+1 cores on the first CPU.

ISBoxer can not use dual CPU cores?

isboxer would run on the system, but wether it is designed to use parallel processing methods .. lax would have to answer

trying to explain so that you will understand why dual core is not so good for gamming
dual xeons are server/workstation orientated, for reliability (lower clock cycles) and number crunching... programs like cad, which have software written to use dual cpus if they are present, games do not. clock speeds on xeons are lower to keep the system stable under high loads.

games do not do any real number crunching, a lot of it has been done at compile time and the game is designed to run on an average pc at a reasonable spec.

An i7 6770 will out perform dual xeons for gamming and cost less,

Re: Xeon E5-2600 v4-processors (http://isboxer.com/forum/viewtopic.php?f=30&t=7823#p36998)

"" They may be similar in price, but the Xeon is heavily gimped in terms of speed. The Xeon is clocked at 2.1 GHz which is absolutely atrocious, and while it does have a turbo speed of 3GHz, you can't overclock it even if you wanted to because it's locked. On the other hand, the 5820K starts off unlocked and capable of 3.6GHz minimum (which is already 20% faster than the turbo speed of the Xeon), and has the ability to push it over 4GHz with relative ease while on air cooling. A six-core CPU that is clocked ~50% faster than an eight-core is going to be faster in probably every benchmark you can throw at it. ""

Honestly, I'm not sure what all this talk about parallel processing has to do with simply setting the CPU affinity. If assigning multiple cores from different CPUs to a single game client becomes an issue, then don't do it, but there shouldn't be any reason why you can't assign 6 clients to one CPU and 6 to another. As for whether it's going to work well or not, I honestly have no idea. :)

This was a reply to a slightly different question about comparing a locked 2.1GHz 8-core Xeon and an unlocked 3.6GHz 5820K, but my reply would still partially apply if the OP was looking to use slow Xeons rather than those running near or above 3GHz. The OP is asking about a CPU which once sold for $1,500 not too long ago, and 2.6-3.3GHz is getting close to the stock clocks of the $1,000 5960X (3.0-3.5GHz). Unfortunately, I still think ~3GHz just isn't enough for running so many clients, because most consumer-level processors that we'd use for multiboxing run much closer to 4GHz when purchased retail, and then have the potential to overclock several hundred additional megahertz, whereas a Xeon doesn't.



EDIT: The thread title should be E5-2670 Dual CPU Builds if some mod would be so kind.
Before I change it, see if you can change it yourself by editing the post, clicking on "Go Advanced," and then editing the title.

Thank you for letting me know how to take care of that :)

As for the rest if I can find a decent dual cpu motherboard (everyone has cleaned them up since these processors dropped to around $70) I'll probably give this a try.

I'm currently using a I7-4790k @ 4.6 but it is pegged when I try to run 6 AO clients. Something seems to happen with this game when you get more clients than cores. I blame 15 year old code.
