Umm how can water cooling not allow a higher CPU speed? Surely it cools better than air ?
i still prefer the 4670
So you're telling me, the 4670K does not support trusted computing?
Overall the K version scores better, but namely if you focus Only on overclocking. How would these fair against eachother if overclocking was tossed out the window, would the K still have the upper hand for the $20 bump in cost?
not bad
