Best desktop proc for mining?

I have an AMD FX 4100 on an asrock 970 extreme3 Running Winblows 7 64k

I am mining with jhPrimeMiner-T16

This is what im looking at.

Is that inline with what it should be?

Guys, dont compare primes/second - this varies on your settings. More important (and comparable) is chains/day. Did you check the mining hardware comparison thread? (See my sig.)
