The more moderately priced P5K practically looks naked compared to its more pricey siblings - and has significantly less in the way of heatpipes and heatsinks on it. In addition, or exclusion rather, ASUS dropped the optical S/PDIF output, the 802.11b/g WiFi support, and one of the Ethernet ports for this more basic board.
Given the lower end cooling solution, I'd hazard a guess that the "Deluxe" editions have a better chance of reaching higher overclocks - which may be a moot point if Asus does not provide extensive overclocking options in the "vanilla" edition's BIOS.
Here is a photo from Asus of the P5K "vanilla" edition.
Conclusion
While I'd love to tell you more about the P35 chipset, and Gigabyte's interesting P35-DS3R, along with the ASUS P5K family, those pesky little NDA's requires us not to reveal more until those NDA's are lifted.
But don't worry.
I'll be putting the P35, with both DDR2 and DDR3 memory through some serious torture testing to find out how well the P35 and DDR2 & DDR3 perform.
Frankly, I can hardly wait to find out if Intel has managed to outdo its excellent P965 chipset; and how well Gigabyte and Asus did on their first P35 implementations.
