So I was just looking around the web at motherboards and I found some motherboards that say DP, so I went ahead and Google searched it, and it turned out to be dual processor. So does dual processor mean I can put in two processors in a single PC? E.g. 4790k x 2? Is that how it works?

Also if you could put dual processor would it help with anything other than servers? First time hearing this!

Thanks!

dual processors only works with Xeon E5-E7 series, all intel core I series and xeon e3s can't do dual processors.

dual processors is for huge servers/workstations only. So having a dual cpu is very very expensive.

If you want some serious processing power, just use a GTX titan or Tegra GPU in conjunction with your processor.

Yes it basicly means that you can have two of the same processors in the same Motherboard, though the processors need to be the same speed not like one of them to be 800MHz and the other 1.2GHz, even though some cases support it :) 
So its a motherboard witch offers you to have the double CPU speed but the CPU's need to be the same model and speed :)

Yes, server boards can have more than 1 CPU working at the same time. Those CPUs must be compatible with the sockets, i don't know if they must be same CPU or can be different models.

Also, server boards can have a lot more RAM slots. At consumer, we have a max of 8 slot (Intel-E boards), but servers can double or more.

Ohh alright :p  I thought so :)  That's a crazy lot of processing power though. And I heard IBM's chips are 200X faster than intel's best server chip >.<

It's not necessarily very very expensive considering the lower e5 are ~$200, although cost ineffective because the mobo is $300 and they are low clocks with no ht. For that price you could get a 6 core i7 that would be better. DP is not only for servers, it's also for workstations. You can install windows on it fine so you could do anything else on it but nothing needs all that cpu power besides these 2 uses. They have more ram because each ram channel can have 2 dimms. So each cpu has 8 dimms with quad channel cpus for a total of 16 dimms. There are also 4 and 8 cpu configs.

Also tesla not tegra. Tegra is the mobile gpu. Although I might suggest xeon phi.

I barely even have money for an I5 build :p  Thanks though Hobbes the tiger :)  Just asking out of curiosity!

Ibm cpu are not 200x better. They have pretty much always been on par with each other but the difference in architecture makes the ibm better for database workloads. Although the majority of supercomputers are xeon with the current number 1 being xeon.

Alright, I guess I was being misled then. Thanks for all the help!
