This brings us to the ECS PF22 Extreme CrossFire ready motherboard. Unlike ASRock's 775i915P-SATA2, which was based on the old Intel 915P Express chipset to deliver an entry-level CrossFire motherboard, the ECS PF22 Extreme makes use of the current performance Intel 955X Express chipset. While this means that the board falls into the non-native CrossFire category, ECS can bank on better performance and the extra publicity surrounding the Intel 955X Express as it is officially listed by ATI as being CrossFire compatible..
