I think you will be good to go with these radiators. Myself: I have something similar planned - not done yet ... have the fans and cases but not the case or motherboard. I will be cooling a 5820K (so same heat as you) + Dual SLI 980 Ti with 1 HWLabs Nemesis GTS 360 and 1 HWLabs Nemesis GTS 240. So you will actually have a bit more headroom than me. (I am limited by my case dimensions - a CaseLabs S5 - so I cant fit in a 480).
Just be aware that your combination of 3 blocks plus the 2 Nemesis GTS radiators will be quite high restriction so you may want to think about pump power to allow for this.
