"Performance-wise, the P5E3 is a mixed bag. Running DDR3 memory at the same timings as comparable DDR2 kits did not really cause a performance loss per se, but once the memory speeds and CPU clockspeeds are increased, the board just comes alive with performance increasing at leaps and bounds. If you count the overall wins and losses, the board does not fare as well as some of the boards tested. Performance against another X48 board shows comparable performance, so on that front repeatability is a big factor. Overclocking on an X48 chipset comes with its own set of rules despite the fact that it's cousin, the X38, offers similar performance."
