Although upgrading the CPU will help overall performance, you should also fix your Athlon X4, it should score around 50% but it's only scoring 39% which means that for some reason it's not able to reach normal turbo frequencies (seems to be stuck @ 2.65 GHz). Ensure that you don't have any power saving enabled in windows power options (check the Maximum CPU setting). Also ensure it's not overheating and that there are no non-standard bios settings preventing the CPU from reaching its normal boost frequency.
Ok, I was on balanced power, I adjusted that to high consumption to make sure that isn't causing and issues, I checked the bios and they all show they are running 3.7 GHz, I ran another benchmark and it is showing at 46% the first starting test and 52% the latest, which from what you said sounds on par.
