not really sure what that's got to do with DX12. Why do you think that this is the case.
With multiple processors, the problem is how they access a common memory pool, and common caches, that's a much more significant problem than DX12 can deal with.

Thats why I'm asking. don't know a lot about Dx12. But I've heard that Dx12 allows you to spread the workload on more cores. So if you got dual Xeon's, it is spread over both cpu's? About the memory pool I don't know a lot aswell, maybe it helps if I give you the CPU names?

I would categorically state that a dual xeon machine would not be a good gaming rig, regardless of the impact of DX12. DX12 might lift the performance of weaker 6/8 core CPUs compared to 4 core cpus by allowing the load spreading, but a strong 4/6/8 core would be better.
What are you thinking?

if it's a freebie, then it'll be ok just don't expect to be gaming with 8 cores and 16 threads, it is an old CPU (2009), so how well it will stand up in single threaded performance I don't know, but I wouldn't expect much. Just don't go out and purposely buy a dual CPU system for this purpose.

1. watch the language.
2. Each cpu has it's own pool of memory, so the game would have to be in two places at once, and each instance would have to update the other.
3. dual CPU systems are so rare, why would you develop such complexity for it?

As promising as it may sound, DX12 is not a miracle waiting to happen. Far from it. It's all ultimately depends on the developer on how they code the game to run. Judging by how early DX12 games perform, the result are mixed bag at best. Not every developer has the same level of expertise on this matter. Some team are better, some just barely. Some doing great on some aspects while sucks at others, and vice versa.
By the look of it, I say the future is rather bleak. Just like people. A few winners, a whole lot of losers.
In the end, it's up to you and me as users and buyers to choose to our liking. Don't like it, don't buy it. Like the idea of a game but the execution sucks, vote complain with your money, don't buy it.
That simple, really.
Don't concern yourself with technical aspects. There are people dedicating their lives already does it for you.

It wont help.
The greatest problem is that once you reach a certain amount of CPU cores, it takes more time to spread the workload between the CPU cores and swap between cores that the work itself on the core.
This means that, in practice, even if a developer made multi CPU core (and dual cpus for that matter) support for their game/application it still wouldent be that great.
Here is a very good test about what you are wondering about: https://www.youtube.com/watch?v=L2Kr_yjQiDU (its in programs that are supposed to use as many CPU cores as you have, so games would be even worse).
