|I see very little reason to upgrade. You could add more RAM at a minimal cost though - 2x4GB to the 4GB you already have, 12GB will be plenty! The graphics card is a bit dated but still ranks high on the charts:|
You have a Black Edition CPU but it appears you're running it at the stock speed of 3.1GHz - why? The whole idea behind the BE CPUs is their overclocking ability. You should have no problem running it at 3.4-3.5GHz & probably wouldn't even need to adjust the voltage or any other settings. You may even be able to unlock the cores & turn it into an X3 or X4.
Your graphics card can be overclocked as well. Create an overclocking profile & just load it for gaming. Return to the stock profile for non-gaming.
