Yep! Another great way to test it is to use memtest.exe until you've got all your ram being tested (don't let it start swapping) and then watch your cpu temps soar. I found out my 4790k was heat throttling using this method.
CPU-Z/bench/stress CPU also imparts a decent load on all cores, albeit not quite as stressful as Prime95, yet still more loading than that of most games..
