OK, i get what you wanted, so this dissecting of calculations was more meant as harsh joke :), but if you wanted to divide rads proportionally to cooled components heat dump you should at least (if rads are of same model line) count their area. as in instead of 560 use 4*140^2, 1*120^2 and such. And to find out proportion one has no need to replace mm2 with W :)
+ascl already noted, that cpu o/c is more low temp needy then gpus, even though heatdump is similar. Though then again, with that big rad area i doubt both ways will differ much more then 2-4 degrees C be it of single or dual loop. Also nothing beats real world testing numbers - you can simply try both setups.
