I agree with you on the Haswell-E and Asus Rampage MoBo. Also all the DDR4 would be of "higher frequency" than DDR3 as DDR3 standards stop at 2133MHz and DDR4 starts from there And the GPU I was considering was either 2xTitan Z or 2x R9 295X2. So to power them I thought I'll need atleast a Corsair AX1500iWith your budget and requirements, it would be best to wait for haswell extreme 8 core i7 5960x with Asus rampage 5 extreme and 32gb of quad channel high frequency DDR4 memory.
Coming to the gpus, to power two 60hz 4k displays,you would need 4 GTX 880Ti's(maxwell flagship) or 4xAMD 390X or whatever it would be named.
Powering this rig would need a hefty power supply.Corsair AX 1500i or EVGA Supernova 1600 T2 would be the best in this scenario.
