HotHardware.com posted a review on the Intel Core 2 Quad Q9300 Processor

Intel's Core 2 Quad Q9300 has some rather large shoes to fill. This newly shipping, relatively low-cost quad-core processor from Intel is a replacement for their long-standing price to performance champ, the Core 2 Quad Q6600. The Q6600 was the first quad-core in Intel's arsenal which was actually affordable, and even today, it remains one of the best values on the market. Not only is the Core 2 Quad Q6600 inexpensive for a quad-core CPU, but it is extremely overclockable and provides a significant amount of computing power for the dollar. Core 2 Quad Q6600's are still in high-demand - a trend which is likely to continue until they are no longer available.

Like we said, rather large shoes to fill. Luckily, the Core 2 Quad Q9300 processor has some impressive new features under the hood along with a higher clock speed. Head on over to the site and check it out...
