Asus P5W DH Deluxe, 975X Core 2 Duo Ready Motherboard

Introduction and Specifications

Six to nine months prior to the launch of Intel's Core 2 Duo product line, if you polled the average reader, regarding their thoughts on an Intel 975X based motherboard, you might well have gotten a luke-warm reception.  Back then AMD's dual core Athlon 64 X2 and FX offerings were in full stride and NVIDIA's nForce 4 chipset found its way into many high-end Desktop systems.  On the contrary, no one would argue that Intel's 975X chipset was not without its own merits for die-hard Intel customers.

Let's face it though, without a more efficient and capable CPU under the hood, Intel's market share in both processors and chipsets, was being whittled away and with good reason.  The introduction of Intel's latest flagship line of dual core processors, dubbed Core 2 Duo, also know its code name of Conroe, has breathed new life into Intel's adjacent chipset business.  Intel's "ecosystem" has gotten significantly healthier in the past few months to be sure.

Today we're taking a look at a new motherboard from Asus based on the same Intel 975X chipset that has been out on the market since December of last year.  While typically many of you might conjure up a yawn at the thought of a 10 month old product, with Conroe driving the performance testing, we're sure you'll all sit up and take note.  Asus' new P5W DH Deluxe is on the HotHardware test-track today and a Core 2 Duo E6700 is at the wheel.
