ECS has been only been releasing quality high-end motherboards for the last couple of years. The truth is, in the past ECS motherboards have been relegated to the bargain end of the market by most hardcore enthusiasts. Many of their previous boards came without the overclocking features that the high-end motherboard market wants. ECS recognized that their image needed some work and decided to change it recently by releasing boards more on the high-end. To that end, the Extreme series was born.
Intel released their LGA-775 platform in April of 2004 along with the HDA (High Definition Audio) successor to the AC'97 standard, PCI Express, the successor to AGP and the BTX form factor, which hasn't really caught on to the market, as ATX still makes up the majority of the market with few cases using BTX. They released the 965P chipset in the middle of 2006 with the Core 2 Duo CPUs. The board on the test bench today is the ECS PX1 Extreme based upon the 965P chipset.
