Since the arrival of Intel's P55 chipset and the LGA1156 platform almost a year ago, over a dozen different motherboards based on that product line have passed through our testing lab. Some of the best offerings we've come across include the well equipped MSI P55-GD65, Asrock's value priced P55 Extreme, and the Asus P7P55D Deluxe which received high honors for its amazing overclocking abilities and excellent board design.

Today we shall review the Foxconn H55MX-S motherboard based on the Intel H55 chipset. The company has been making inexpensive products of late, so it only has a couple of more or less top-class Socket 1156 motherboards -- the P55-based Inferno Katana series.

The second 890FX board that we've seen is from Gigabyte. If you missed the first one last week, check back to the MSI XPower X58 preview. Compared to the MSI board, the Gigabyte offers an extra 16x PCI-E slot, although as expected, the bandwidth is less: two 16x, two 8x, two 4x. There is a fair distance between the main 16x graphics slots to allow air between a pair of dual-slot graphics cards. In addition to the AMD 890FX Northbridge, the SB850 Southbridge provides six SATA 6Gbps ports, and the ability to create RAID 0, 1, 10 and 5 volumes, plus a couple of extra USB 2 ports over the previous SB750 Southbridge.

Zotac isn't chasing a high performance, high investment and few sales market with its motherboards. In fact, it's arguable the only designer/manufacturer (well, the latter part is technically fulfilled by PC Partner) of motherboards that puts its time exclusively into small form-factor (SFF) products. We first saw their micro-ATX GeForce 9300 board, which was then followed by a mini-ITX model, and later a feature-filled Ion board that had everything but was unfortunately just too expensive.
