hey guys!
so i'm looking for the best all-in-one-computer combo which let me do all the things at the same time parallel while using several monitors (e.g. 1x 4k and 3x 1080p).
what i'm quite sure about is that i want a sli board to use 2 gtx 1070s (i know not all games support sli at this point) which will be upgraded to 2 1080s or even 2 titan x's in future. and i want to use the fast m.2 ssd as a boot drive. i even would like to be able to use 2 of them in raid 0 but i dont know if there is a mb already out there for that use. in any case i'd like to be able to raid 0 my secondary data ssd's. the decision left is whether to use an 8core i7 (6900K or 5960X) and a single cpu mb (about 1000eur for cpu + 300 for a mb = ±1300eur) or two 6core i7 6800K's (about 2x 400eur cpu's + 500eur for an asus Z10PE-D8 WS dual-cpu-mb = ±1300eur) on a dual-cpu-mb combo.
can u help me sort out which will be the better solution for my tasks?
maybe even a single 6core cpu is enough? or a dual 4core (i7 6700k)?
thx in advance.

You cant do that on standard computer hardware,and the motherboard you listed is not good for an i7 since i7 cpus are limited to one CPU per motherboard.What you need is either a dual xeon motherboard,or a single xeon with many cores.The problem with both is the relatively slow clock speeds of the Xeons (none are above 3.6 Ghz at best),which might hinder your performance in games,since they do not scale well beyond 4+ cores.

does anyone know if the 2 cores extra of the e.g. 6900K instead of the 6 cores of the 6800K will benefit my multitasking potential at all?
or are even 4 cores enough so i could go with the new kaby lake cpu's?
