Turn it back on again

Please note that from what i read, hyperthreading should only be turned off if you have a 4 core processer and the game only utilizes 4 cores. For two core processors and when playing games that are programmed to utilize 8 cores hyperthreading will provide better performance than turning off hyperthreading and overclocking further. This is why some people may or may not see an improvement. For il 2, only people with 4 core processors should see an improvement with no hyperthreading and overclocking. But for games like bf 3 hyperthreading will provide better performance.

How about an i3 at 2.1 GHz? It gives me slowdowns in old (probably single threaded) games, I suspect that's because hyperthreading gives me four virtual cores at about 1GHz, where no hyperthreading would give me two at 2.1.
