Intel has taken the time to drop the prices for their Core 2 Quad, Core 2 Duo and Pentium processors, all while not drawing too much attention to the change. This makes some of the Core 2 Quad processors a considerate amount cheaper than before. See below for full price changes.
For some reason the Core 2 Quads Q9650, Q8300 and Q9400 have had their prices dropped more drastically than the others. The Q9400 and Q8300 processors are still in direct competition with the newest additions to AMD’s line. This gives AMD little choice but to cut the prices on the Phenom II line in order to compete. The Core 2 Duo E7500 has a higher clock speed than the E7400 whose spot it took at the $133 price point.
As a leading name such as Intel drops their prices it will force their competitors to soon follow suit, thus dropping the overall price for these products. I would say this is the time to snag one, as you will soon be after the newest and greatest thing at an even higher price in coming months. It appears that Intel did not want such pricing to be shouted from the hilltops.
