I recently bought an AMD A10 7850K APU for my desktop. When I had put it together, I tried to play a game and found out it was very slow (slower then the one in my laptop @1.5 GHz). I took a look at Task Manager and saw, there was only 2 cores. So I checked resource monitor, Device Manager, and CPU-Z and they all said I have 4 cores. Can anyone help me figure out why only 2 are being used?
