The Gigabyte GA-EP45-UD3P is an ATX motherboard that supports Intel LGA 755 format processors. This motherboard is designed to support a home theater PC build, and is similar to the Gigabyte GA-EP45-UD3LR. FireWire connections are now supported, which makes the computer compatible with a number of video cameras and other peripherals that need a high speed connection. A second Ethernet port has been added as well, with Teaming enabled to increase the amount of bandwidth that can be achieved for downloading or streaming. While there is still a single PCI-E x16 slot running at full speed, an additional PCI-E x16 slot running at x8 is available if needed, although systems like CrossFireX or SLI are not directly supported. As with previous versions, high definition on-board audio support is available through optical or coaxial connectors.
