I planned to use StarCraft II as well but frames seemed limited at 60 FPS so I left those results out since all three settings easily reached that mark. Let's get things started with 3DMark 2006, a program that is well past its prime but is still a fun test to run simply because nearly everyone has run it at some point and can relate with the scoring system.
Here we see a pretty big improvement going from stock to max non-volt modded overclock. Adding more volts and higher clocks barely improved the score.
The newest 3DMark for 2011 shows a little more improvement between the two overclocks but still not as much as I was anticipating.
The trend continues in FurMark where we see a big jump from stock to "mildly" overclocked. Let's see how things shape up in some real-world games, starting with Crysis. All tests were run full screen, 64-bit with DX10.
Crysis was playable at the max overclock with 16xAA enabled. Without it, things were a bit smoother at nearly 40 FPS and nearly 70 FPS on High settings.
Although the plot and story line were highly criticized, the graphics of FarCry 2 were excellent for its time, with changing weather patterns, day and night time cycle and a unique fire propagation mechanism. A variety of landscapes, wildlife and highly destructible environment keeps things interesting and entertaining. The Dunia game engine used in FarCry 2 is less demanding on hardware than the Cry Engine 2 used in Crysis.
Testing was done at 1920 x 1080 resolution, max graphics, DX10, and 8x Anti-Aliasing both disabled and enabled.
FarCry 2 was 100% playable at the maximum graphics settings with 8xAA enabled, even at stock clocks. With older games like this, there really isn't any need to overclock as you won't notice the difference between 60 and 70 FPS.
I tested Mafia 2 using the demo via Steam. The tests were run with max graphics, AA enabled and PhysX disabled.
Unfortunately I'm not the biggest PC gamer and as such, I don't have a plethora of titles on hand to test with so we will wrap it up here. Let's move ahead and wrap things up with some final thoughts and a conclusion.
