As stated, it really depends on what you do.
For non-OpenCL/CUDA rendering, more threads/cores will net you more performance, so you'd be better off with a hex or octo variant on the 2011-3 platform.
I'd probably just get a 2011-3 board for additional RAM capacity (density of DDR4 as well as more slots) and future expansion. Supposedly Broadwell-E will be supported on 2011-3 so you'd also have a bit of an upgrade path, not to mention an octo core extreme edition if needed, whereas on 1150 you're simply limited to quads.
