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.
