No it isn't necessary, but several factors led me to test with two pumps:
1. apple to apple directly comparable data
2. I do like the redundancy factor for a high-end loop
3. my bench is setup with MCR Drive units. it's so easy to setup, it's a dream come true (for me).
I removed the XT from the loop now, as I am testing the new Apogee LP (low profile for 1U and space constrained applications), so this will have to wait for now. but I do see the economic value of it, so Im not against it.
But to answer your concern more directly: if you now have SLI graphics cards connected in series, you would benefit from parallelizing them.
