I'm running a older AMD A4-6300 3.70GHz with 8GB ram using 4 hard drives. I had this updated from my previous computer and never thought of asking about Bluetooth then. Now, being disabled, I probably would find it useful, so am wondering if this is something that can be added to my existing system or would I need to update my board again. I don't play very many games etc so computer is mostly surfing web, fb etc. Any advice is greatly appreciated
