Both will be almost equal comes down to cost , the intel would be my pick new cpu socket so u can upgrade down the road

Cpu 4770k @ 4.7
Gpu Gtx 780s SLI

The asus is a better board go for it better software
And overall layout

I use realbench from asus and also run 3dmark and some others as long it don't crash or see
Artifacts should be good check out oc3d youtube overclock gtx 780 big help a lot
also you must oc each card not in sli find each max stable then find the average of the 2 because each will run different

I have 2 gtx 780s and 4770k
Bottlenecks no none at all
Stress test for gameing
Run
Aida64 benchmark
Run passmark benchtest
Run 3dmark
Run cin bench 11.5 benchmark
If u pass all that no bluescreen and driver failure and temps below 82 then u will be stable to game might not be full system stable but gaming u will be good
For full system do all that +
Intel new stress test in there extreme unity run for 8 hours and 2 for the mem

Well I would be very worried going close to that if I couldn't get it stable before 1.35v then I would call it quits lol

Welcome to the team red lol
I would say for cooling do a custom loop or a h220 or h100i

could be the mobo most the mid boards are only 8x +8x pci with u sli that slow it down some. but is should not be stuttering when playing.
downclock the chip and mem  like - 50 and see if that helps that tell u if gpu or is maybe some thing alse
if down clocking works then u got gpu prob . if still doing it try nivida settings if still  after that try your ddr3 ram add little more volt. take it from like 1.5 to 1.53
 
i also have 2 gtx 780 and they run any thing lol.. 

check some your nivida settings
