What do you think of this build? Can I improve?

why not get 2400mhz rated memory with all that hardware.

the motherboard is a bit overkill unless you want to run like 4 GPUs.
a $200 ASUS board is plenty enough even for SLI

as is 32gb of ram... unless you have a specific reason for getting that muchm 16gb is MORE than you'd ever use for most people.

1200w PSU... again, overkill

i'd drop the mobo down a notch, go to 16gb ddr3 2400, and 1000w psu.. and with the money you saved grab a second 780
