The Z87 motherboards had gotten a bios update(albeit you won't get the update immediately, you'll need to find a way of updating) but it would be best to get a z97 motherboard.
To answer your question, dsp lle on seperate thread can cause quite a bit of crashes in some games, not necessarily it won't give you a bigger performance increase. the i5 4690k is perfectly fine with some games on lle without it on a thread. i know pikmin 2 crashes a lot with dsp lle on thread enabled. i haven't tried the 2 games in the title yet though. i don't have a sensor bar yet xD
but the processor should handle it really well. you might be able to run dsp lle on thread on those 2 games. im not sure, never really tested them.
Hope this helps
