ALTHOUGH DISCUSSION of Intel hardware lately tends to degenerate into Prescott-bashing, the company's new 900 series chipsets really are the bee's knees. Released several months ago, the new chipsets boast plenty of PCI Express for peripherals and graphics, Native Command Queuing for Serial ATA hard drives, support for DDR2 memory, and support for Intel's High Definition Audio spec. With companies like VIA only just beginning to preview PCI Express chipsets, Intel is way ahead of the game when it comes to support for next-generation standards.

While the Athlon 64 world waits on PCI Express, a wide range of motherboards based on Intel's 900 series chipsets have flooded the market, and they're more affordable than you think. For only $132, you can get your hands on Abit's 915P-based AG8, which serves up PCI Express graphics, all the integrated goodies in Intel's ICH6R south bridge, and support for DDR400 memory so you don't have to resort to high-latency DDR2. With recent price cuts making LGA775 processors like the Pentium 4 520 2.8GHz available for as little as $160, boards like the AG8 could be perfect for video editing enthusiasts, Hyper-Threading fetishists, and those with a deep longing for PCI Express. Read on for an in-depth look at the AG8's features and performance.

The AG8 offers about what one would expect from a 915P-based motherboard, including PCI Express X1 and X16 slots, four-port Serial ATA RAID, and Gigabit Ethernet. The AG8 accepts plain old DDR memory, so you don't have to worry about upgrading to DDR2. Abit is also skipping out on Azalia (a.k.a. High Definition Audio), instead opting for a rather pedestrian six-channel codec that won't do HD resolutions or sampling rates.

We'll cover each of the AG8's integrated peripherals in depth in a moment, but first, let's see how Abit lays everything out on the board.
