Which PC for host?

[ncngrr]

I have 3 PCs:

1. 4770K, 2 x GTX-760s
2. 4790K, 1 x RTX-2070
3. 9700k, 1 x RTX-2080

I need to power 5 x 1080p outside view monitors.

Which PC should be the P3D host?
Which two PCs should be the clients?
How should the 5 monitors be distributed across the PCs?

Thanks.
