EARLIER THIS WEEK, AMD launched its long-awaited Socket 939 platform, and there was much rejoicing. But the rejoicing was followed by a heavy sigh, for as promising as AMD's dual-channel Athlon 64s are, the cheapest one rings in at $500. If you look at the price and performance of Intel's current Pentium 4 lineup, $500 for a 3500+ doesn't seem all that unreasonable. However, $500 can also buy an Athlon 64 2800+, 1GB of DDR400 memory, a shiny Antec Sonata case, and one of Abit's new KV8 Pro Socket 754 motherboards.

At first glance, our $500 bundle looks like a much better deal. After all, even slower Athlon 64s perform quite well, and the Sonata is simply gorgeous. But what about the KV8 Pro? Is it really worthy a worthy addition to our little all-star bundle?

Yes. And then some. With competitive performance, a working AGP/PCI lock, the most feature-rich BIOS I've ever seen, and the ability to lower the CPU multiplier, the KV8 Pro could very well be the best Athlon 64 platform for budget-conscious enthusiasts and MHz-starved overclockers. Read on for a detailed look at the KV8 Pro's features, performance, and intriguing overclocking potential.

The specs
Before diving into a tour of the KV8 Pro's layout, let's have a quick look at the spec sheet.

All the usual suspects, almost. The KV8 Pro has everything you'd expect from an enthusiast-oriented motherboard, including six-channel audio, Serial ATA RAID, and loads of BIOS goodies, but the board curiously lacks integrated Firewire support. Also missing is a secondary IDE or Serial ATA RAID option, which may or may not handicap the board, depending on how many drives and arrays you want to run.
