At the end, only a benchmark can tell.

These are a bit older processors, but they have the advantage of 4 
memory channels (instead of 2). Since we know that when all cores are 
used, the speed is limited by the memory, it could well be that they are 
faster in these cases (and usually, due to parallelization, this is the 
usual usage of a cpu).
For some reasons, Intel did not come up with newer "X" processors so far 
(maybe they want to sell their more expensive Xeons).

It could be a good choice, however, I'd expect the cpu and the 
motherboard will be a bit more expensive ?
