The 8320 is still viable chip you will need a new board I suggest a 990fx board to get the most out of your chip because they overclock well most of them do I have one sitting at 4.4 ghz in one of my systems but.... its a dead socket they wont be making any newer chips for the AM3+ Socket any more because AMD has the ZEN chip coming out this year it will be A new socket .... Your best bet either wait and overclock the 860 you have and see what happens to ZEN or go with a I 5 4460 or higher.
