What cpu is better?

Solution
The 6400 can turbo to 3ghz on all 4 cores - it is ever so slightly weaker than the 4460 on paper.
In real life you could stick the 2 side by side & not see a difference.

Both good cpu:'s , the 6400 is on the latest socket so theoretically would be the better choice for upgradability


However both will last you 4-5 years easily IMO so go for what fits your budget best. Socket 1150 boards & DDR 3 ram are cheaper than skylake boards & ddr4 so its budget dependant.
There will not be any noticeable difference in performance and therefore they will last just as long. Only plus going with the 6400 would be get a DDR4 motherboard and possible better upgrade-ability in the future.
