From a fluid pressure stand point, 1 pump should do it. However, there may be some clear temperature advantage for the CPU not to be in the same coolant stream as a pair of 300W GPUs. I’m not sure if a dual system is what you had in mind, but something to consider if you don’t have a lot of cpu temp headroom.

I have an XR5 280mm, XR7 480mm, 2 GPUs and a Threadripper ... 1 pump handles it fine. I did do a custom curve for it as the default curve didn't seem to have enough oomph to keep the GPU spinners spinning (though the liquid was flowing).

1 XD5 unit will be more than sufficient for your system. 2x radiator + 3 water blocks.

From our Custom Cooling FAQ
Q: How many water blocks and radiators can one Pump/Reservoir Combo support?
A: This unit delivers a head pressure of 3.9 meters, powerful enough to provide adequate flow through a custom cooling loop of at least four water blocks and three radiators.
