System performance
SiSoft Sandra's complete system benchmark is a good indicator of CPU performance. The final aggregated score reveals the FX-8320E is, once again, the slowest of the bunch. The gap between it and the FX-8370E isn't much, mind.
Cryptography is an area where Haswell excels and not even the fastest FX part can touch on the slowest Core i5.
Fire Strike shows decent scaling with CPU performance due to two of the four tests, the Physics test and Combined test, being heavily CPU-bound. The FX-8320E rocks up in last place by a 200-mark margin.
