TweakTown posted a review on five Intel P35 motherboards from Gigabyte, ASUS, ABIT, Foxconn and ECS. Here's an excerpt:

Gigabyte P35-DS4 - Gigabyte's mid-range DS4 board is based on the DQ6, slightly cut down but still retaining the excellent features of this series. The onboard features are fantastic and its price while a bit on the high side is pretty competitive.

ASUS P5K-E - The ASUS P5K-E board is a feature packed board with a slighty high price tag, but definitely worth the extra cash, especially if you're going to want wireless as the ASUS board can run as a wireless NIC or a wireless AP, depending on your needs. Its performance is just about on the heals of the Gigabyte board, if you want the wireless this board is for you.

ABIT IP35 Pro Off Limits - Unfortunately ABIT's board while quite nice didn't stand out to us, its overclocking was good but the price tag for an ABIT board is just too high. Without any additional features like the ASUS board, it's not really worth the money unless you just want the ABIT name.

Foxconn P35A - Foxconn's board resembled more of the higher end boards, but its BIOS and overclocking really let it down as the lack of some voltage features and bus tweaks really put this board in our bad books. Sorry Foxconn but better luck next time, its only saving grade is a lower price tag.

ECS P35T-A - Lastly ECS, this didn't surprise us as the board from the start looked like a budget to mid-range board, and it didn't have any great features to bring to the table. Being cheaper in price means it's a good platform to start with for a cheap crossfire setup.
