Thanks for clearing that up Maxinc and Kenzie.
Rodders: The only overclocking I've done is to mess about in Asus'es software but not actually know what I was doing. One thing I did learn that by clicking the wrong things it made the temperature shoot up with the stock cooler followed by the computer acting very strange. At that point I thought it best to leave alone.
So I'd rather just buy a quick CPU to start with. I'm still a bit undecided weather to go for the i7 2600 or the 2600k. I'd prefer not to spend the extra money but from what I read the 2600 has limited overclocking on it. Decisions decisions.
