Difference Between Xeon versus Desktop?

[RunawayPrisoner]

So much faster at the same clock speed? I'd run the game at the lowest resolution possible, too, if I want to test my CPU out.

Okay... found a professional review after some tedious searches:

From what I can see, E6600 @ 2.4GHz only outperforms X3220 @ 2.4GHz by a little tiny bit in gaming... almost invisible differences. E6600 was also faster in some cases, too... and I'm just guessing that Q6600 would yield the same result... somewhat. But I don't think it can be up to 25% in gaming. As far as I know, Crysis is the only game that might benefit just a little from quad-core processors.
