The price of the Core 2 Quadro Q6600 is likely to be higher than that of the premier Core 2 Duo, $530, but lower than that of the Core 2 Extreme, $999. The chips should be drop-in compatible with applications that support quad-core microprocessors, e.g., mainboards based on the Intel 975X chipsets that can work with Core 2 Duo.
