I have been considering upgrading my old cpu(q6600) to a x5460. I wanted to know which would be better and if it is worth buying the x5460 that is $10-$15. I plan on overclocking the x5460 to 4ghz and my q6600 is already at 3ghz, so if you compare these 2 at these clock speeds which would be better? I know the best option would be to build a whole new system but I am tight on money, so I would like to know if i should keep my q6600 or buy a x5460.
