Question about 10 box setup CPU and Framerate

Well I'm ready for MoP 10 box. I did 6x shamans before. Stepping up to 10. 9x Shamans 1x priest. all 85 with MoP Expansion.
I have 3 monitors and been wondering about CPU usage/load.

Question,
When you setup windows/regions, do you setup on separate screen or have everything on one? which way puts more stress on CPU? or it doesn't matter.

also, how do you have your characters set on Performance CPU cores limit set on Framerate in foreground and background : I'm thinking to set main at 60/30 and slaves 30/15, or change it to lower? how do you have yours setup?

You can go with "Full Screen Stacked", and combine that with an area (main monitor or secondary) filled with a DX-Nothing window (blank window).
And then use video feeds from the desired clients onto the DX Nothing area, to show important information.

You could go with regions too.
Which is a larger region and several smaller regions which you swap between.

If instant swap is enabled, every region/layer is rendered at full size; stacked or regions both use similar system resources.
Meaning swaps are instant, mouse broadcasting rocks compared to anything else, and you put the most strain on your system.
Most other software will render each region at the size of that region, meaning swaps and mouse broadcasting isn't as quick or accurate... but the strain on the system is less too.



I've had, foreground 60 and background 20 for quite a while.
I don't make a distinction between master and slaves, because I've used regions and want the active one to look better than the inactive ones.
