VR-Zone has a review up on the Gigabyte P4 Titan series with 8IEXP based on 845E chipset and 8IHXP based on 850E chipset. Gigabyte is the first motherboard manufacturer to equip ICH4 SouthBridge into their 8IHXP chipset so it can support USB 2.0 just like the 8IEXP. Both boards sport a blue PCB and are very well featured with USB 2.0 ports, Audio, LAN, RAID, Dual BIOS etc. Gigabyte 8IEXP & 8IHXP P4 Titan Review
