You need to look for a board that has the features you want/need and is comatible with the processor you have choosen. In your case any 1155 socketed board should be fine. When you see a board you like, go to the manufacturer's website for that board and check the information they provide. (Newegg provides a link on the 'details' page to the board's site.) Especially check the CPU list to see if you will need a later BIOS when you get the board. In the case of the i3-2120, that's highly unlikely.
Btw, the i3-2120 is a screamer all out of proportion to its cost when it come to gaming.
