Thanks for that, I'm just not an experienced overclocker really. However the way you've said that makes me think I could do it. So which motherboard would I have to get and would I have to do any extra configuration after that?
Thanks for the help so far.
E6400 is roughly 20% faster than e4300. The diferences are that E6400 supports Virtualisation and can benefit of faster memory because it has faster FSB(1067Mhz instead 800MHz).
So calculate which one is more worth for the money and buy it.
