Our Summary and Conclusion
The Asus P5E3 Deluxe is a power user’s motherboard if there ever was one. This board sports a number of features not found on any other motherboard currently, including an embedded Linux-based mini-OS and integrated 802.11n WiFi. The P5E3 Deluxe also has a well appointed BIOS and it turned out to be an excellent overclocker. The only issues we had with the board had to do with its oversized cooling apparatus which crowds the CPU socket area somewhat and what will undoubtedly be a high price. We don’t have street pricing yet, but expect the P5E3 Deluxe to hover in the neighborhood of $320. However, enthusiast class chipsets like the X38 and high-end motherboards always command a high price; early adopters are familiar with this trend we’re sure. In the end though, we’d have no trouble recommending the Asus P5E3 Deluxe. If there’s a feature you want, this board probably has it.
Update 10/15/2007: We have completed our testing of the replacement X38-DQ6 with much better results. We acheived a peak front side bus frequency of 500MHz while overclocking with the board, and as our benchmarks have shown its performance is very good, even with more affordable DDR2 memory. It's too early to pass judgement on the X38 due to the fact that we have only worked with two motherboards at this point in time, but it is shaping up to be a solid solution. And the Gigabyte X38-DQ6 should serve users well if they're not inclined to also purchase DDR3 memory for an upgrade.
