Xeon E3 V3 Haswell Series if you're looking for heavily multi-threaded CPUs
They're as cheap as i5 but have the same power as i7 (4 cores 8 threads)
Why they're as cheap as i5 ? Well , Xeon series don't have integrated CPU and can not be overclocked . Basically i7 on steroids
You can find Xeon E3 1220V3 for $197 or an used Xeon E3 1226V3B for only $174 though this one requires H97 mobo
