Would it be possible to dedicate a cpu to dxtory? (On a dual cpu mobo)

[HyperSlayer72]

I have for a while been wondering what the best way to improve my performance in game while recording is.  When recording, and i get an fps drop it often will either be gpu, or cpu caused stutter.  I am getting a either two gtx 1070's or a gtx 1080 ti.  That gets rid of the gpu bottleneck, but as far as the cpu limit goes, I in general have two options, get a single 8 core i7, or two 4/6 core i7 cpu's.  Regardless of cost which would be the better route?  Can I dedicate a single cpu to my general workload and games, and then another to do nothing but capture?  Would the dual cpu idea even work?  Would it be effective? Thanks in advance for any reply's.

I doubt it would work very good if possible.
Remember that you need to transfer data between the GPU and CPU, if they are not on the same MB, it might not even be possible, and if possible, very slow.

1 CPU is much better for Normal (Any Consumer) use as far as i know, even if it looks great with 2 CPUs, hardware doesn't work that well, the closer the hardware is, the faster they work.
And they all need to be in sync sharing data which is essential for workflow, only in some cases are more CPUs good i assume, which would be server loads, separate tasks etc.

I might be wrong about this, but i am pretty sure most of what i said holds true.

Just speaking about the dual cpu thingy, not an answer to your stutter etc issues.

As long as I force cpu processing, and tell dxtory to only use the cores from the second cpu, what would be the other limitations?

In theory a dual socket ( cpu ) setup would work,  but there are a few pitfalls ( such as lower clock speed ).  This article pretty much covers most of it.

Is using a second pc with a frame grabber ( high end capture card ) not an option ?

I need to do some research about frame grabbers, I don't have a very powerful secondary pc, and I record in a lossless format. Also Ill read through the article. I read through it and its very interesting, I have considered xeon processors before, have there ever been any compatibility issues with them on consumer platforms (games, software, ect.)?  If there is, I would consider using a i7 for my main workload, and a xeon for cpu based encoding.  I am not sure if mismatching what cpu's are on a dual core mobo would cause.

Pretty sure the Xeons do support more technologies than any i7 (they'll support any program). Mostly, if the OS supports the software, it'll work on any CPU. Also, you cannot mismatch CPUs afaik.

Anyway, with any of the new 2011-3 i7s hitting the market, you won't need a workstation motherboard. Most (meaning almost all) games do not use more than 4 cores anyway, so if you have a >4-core CPU, recording should not impact the game at all (unless you record something crazy: e.g. 4K @ 60fps*).

*would actually be interesting to see some benchmarks at those settings

You are most likely correct about not needing two cpu's.  I dont have any plans of recording at anything higher that 1080p60.  maybe in the future if I get a 1440p monitor I would record at 1440p60.  The problem is that I almost need to try before I buy with these expensive cpu's to find out what works best.  I would expect an 8 core to be able to play games and record at the same time without maxing out.  My current problem is that my frame timings are going all out of wack when I start recording.  I can be getting 96fps on a 144hz monitor while recording and have that framerate look like 5fps.  Compared to when I'm not recordng 48fps looks perfectly fine.  Also I currently have an i7 2600k stock.

We could take a look at the logs if you want
