Okay, so I bought this new CPU, AMD APU A10-7860k, It is compatible with my motherboard (A58M-E33). The cpu has my games down to 10-20 fps, plus screen tearing. I installed the new drivers, and never changed the graphics card, so it's the same. I bought some thermal paste, put my old one back in, it was fine. So i tried putting the new one back in and boom, slow again (I did apply the correct amount of thermal paste) I am very confused what is going on, please help, thanks.
