Okay, I have $37 that I can spend on upgrading the build, I need to have the i3 compat with the mobo and I`m not spending it on the HDD, PSU, or CPU since I have it already, please gtfo if you don't know hot use 16gb of ram and are telling me its useless.
I assume this is for gaming first, gaming second, and gaming third ? If so, your best upgrade for a little extra money is probably to an H77 board and an i3-3220.
If you want your build more balanced you probably can fit in an i5-3570k and a cheap z77 board if you drop to a 7850 1gb (or similar).
and am not saying that the z77 will be good for the 2100 , just think in the future you will may decide to get one of the i5 or i7 k series to overclock
and about the 2100 can you pay more 9$ and get the new ivy i3 3220.
good luck m8
