"Built with the Intel P45 Express and Intel ICH10R chipsets, the ECS
P45T-A motherboard supports all Socket 775 Intel processors running with a Front Side Bus of 800/1066/1333 MHz. That includes the new generation of 45nm 'Yorkfield' and 'Wolfdale' Core 2 Duo processors. Gamers who plan on running a pair of CrossfireX enabled videocards in tandem (say, a pair of Radeon HD4850's for example), will find two PCI Express 2.0 compliant PCIe x16 slots at their disposal."
