Our comparative test of various boards using the 865PE and 875P chipsets shows that, despite Intel's much touted PAT technology, the Canterwood chipset does not reach the top of the heap in performance tests. The actual $16 price difference between the two chipsets adds up to $40, plus the price of a motherboard. Consumers should therefore choose the cheaper 865PE board - ECC memory detection is hardly a convincing sales feature.
