How many blocks a D5 vario can handle (and its radiator needs)

Hello.

I currently have a EVGA SR-2 with water blocks from MIPS, with 2x Xeon 5620 @ 3.4Ghz with EK Supreme HF blocks, and 2x GTX580 3Gb with EK blocks (not full cover, unfortunately).

My assemble is separated into two individual loops:

For the CPUs and Motherboard, I have a Alphacool VPP655 Single Edition pump (variable speed) into a XSPC 2-bay Reservoir, and XSPC RX480 Quad very high flow rad.

For the VGAs I have a EK pump + reservoir (EK DCP 4.0), and a Phobya Xtreme NOVA 1080 radiator.

I would like to concatenate all into a single loop, because the Phobya 1080 is in a stand, separated from the case, and that is a hassle to move, clean, etc.

My objective is to keep the XSPC radiator, which is neatly mounted atop my case (a XSPC H2), and I may even move it to the below compartment of the case without too much trouble.

With that many blocks (2xVGA, 2x CPU, 2x Motherboard), what should I keep besides the XSPC rad? One pump can handle all of this? Or should I put the two pumps at work on this loop? (I have seen two pumps loops, hence my question). Will this rad alone handle all of this? Or do I need a second, smaller rad?

Thank you all for your help.

A little bit more info:

On an ambient temp of 19 I get between 22 and 31 idle and 30~42 full load on the first CPU, and 2~3C more on the second.
On the second VGA I get 25~35C idle, and max 45C on load (first VGA is 3~5C less).
Motherboard is about the same as the second CPU, as its the last on this loop.
If I turn AC on to 18C, I get somewhat less than that.

I don't mind an increase of 15C on everything, to go one rad alone.
But more than that will make me think twice.

XSPC is on push/pull atop the case flowing upwards. Case is open, so the air on the rad isn't "case hot".
Phobya 1080 is on a stand beside the case, on free air, with 4x 18cm ultra silent thick fans (don't remember the brand).

Pipes are Tygon R3400 1/2 3/4, and all fittings are compression.
