Even with the power of the AMD Athlon X2 and Intel Extreme Edition processors, we still find ourselves hitting a CPU limitation in a lot of our benchmarks. That is, the graphics cards have more performance to give but the processor is letting the team down.
By overclocking the processor we can see what kind of a performance increase we get. When something isn't CPU limited the performance increase isn't all that major but when we do have a CPU bottleneck, every MHz extra we can get can show us an excellent jump in performance.
The Athlon X2 3800+ was increased from 2GHz to 2.2GHz with a slight increase in the front side bus utilizing the stock X2 HSF.
The small bump in processor speed gives us a small bump in performance at both resolutions, with more tweaking there is no doubt you could break some records.
We don't see a huge jump in performance but we didn't give the processor a huge increase.
Far Cry is such a CPU limited game except for the first time we find that the results went slightly backwards when overclocking. We ran the test multiple times and rebooted and the results were consistent with the ones above.
