For users looking to dip their toes in the Sandy Bridge waters, Intel's H67 chipset is the cost-effective choice, and the only option available currently if you want to use Intel's new integrated graphics chip. If on the other hand you want to run off the diving board and do a summersault or cannonball splash, the P67 chipset is what you need. It's more expensive, yes, but if performance and/or gaming prowess is the goal, there is no alternative for the moment.

So what's so great about P67? Well for one, it offers the only effective way to overclock these new CPUs, allowing enthusiasts to increase the multiplier by 4 above what Turbo Boost delivers (Turbo Boost is a requirement). Take for example, the Core i5-2500, which runs at 3.3 GHz but speeds up to 3.7 GHz (100 MHz x 37) with Turbo Boost when only a single core is in use. On a P67 board, the clock speed can be pushed up to 4.1 GHz (100 MHz x 37+4). Those truly interested in getting high clock speeds however will opt for the "K" series processors which are allowed to go well beyond 5 GHz. In addition, P67 allows manufacturers to divvy up the 16 PCI Express lanes provided by the processor evenly for dual graphics cards. An 8x/8x CrossFire/SLI configuration is far preferable to the 16x/4x array offered by H67 boards.

The only thing it loses compared to H67 is support for Intel's GMA HD 2000/3000 graphics which are included in each and every LGA1155 CPU. Compared to P55 for LGA1156, the P67 chipset's PCI Express lanes are fully compliant with the 2.0 standard, delivering twice as much bandwidth, giving a performance boost to connected peripherals like USB 3.0 and third party SATA controllers. In addition, both P67 and H67 support the SATA 6 Gbps standard, albeit only for two ports, and neither have native support for PCI, a standard that Intel is quietly shoving out the door.

We have a pair of P67 boards up for scrutiny, one from Gigabyte and one from Intel, retailing for just under US$200. This puts them in the upper middle class of P67 boards.

Gigabyte GA-P67A-UD4

Priced at about US$190, the Gigabyte GA-P67A-UD4 has premium features like a heatpipe VRM cooler, a sophisticated power phase design (supposedly 12+2), and an additional Marvell SATA controller that provides a pair of eSATA 6 Gbps ports. However, they did a cut a couple of corners by omitting FireWire and utilizing a Realtek gigabit ethernet controller rather than the more expensive but efficient Intel option.

Included accessories.

The P67A-UD4 ships with four SATA cables and CrossFire bridge along with the usual assortment of documentation, drivers, and software.

Intel DP67BG

The Intel's DP67BG is from their Extreme series of motherboards which have broken the old stereotype of the stuffy locked down utilitarian Intel motherboard. Catering to enthusiasts, the DP67BG is equipped with several sets of LEDs, physical power and reset buttons, and even a backup UEFI switch on the back panel. Compared to the P67A-UD4, it has a less elaborate cooling system, only one eSATA 3 Gbps port, but includes an Intel gigabit LAN controller and FireWire. It's also a cheaper board by about US$10.
