I read a thingy on the internet about a guy overclocking a x2 3800 in a review he did about it. I think he had watercooling, and got it up to running at 2.7ghz. He did looooots of benchmarks, when it was running at 2.4ghz(same speed as 3800+) it was performaning almost exactly the same even being slightly higher in some benchies while being slightly lower in others. I will try to find this article.
