I've tested xmr-stak-cpu on a system with dual X5650's (we won't talk about the power usage, it's insane), which is a slightly higher performance chip per core  than an X7350, and I'm getting between 38.2 and 41.5 H/s per core.   I'm running with half the number of threads to not use hyperthreading.

So my dual cpu box is doing ~475 H/s.  

My guess is that if you do 2 threads on a X7350, you might see around 150-160 H/s.    But does that processor support AES instructions?  OP you said you had an X7330 but I can't find reference to that, assuming you meant an X7350?
