Second PCI-E 2.0 slot tops out at x4, making Crossfire X use a bit lame compared to competing boards with full x16/x16 support.

The Gigabyte GA-P55A-UD3P is an ATX format motherboard that accepts Intel CPUs in the LGA1156 format. Together with the Gigabyte GA-P55A-UD3 it is one of the first motherboards that supports the USB 3.0 standard natively without the need of an add-on card. They are similar in most features, but 2 eSATA connectors have been added to this model for faster hard drives. Onboard features include 10/100/1000 Ethernet connections and high-definition 7.1 audio, but video is not directly supported. A number of PCI-E expansion slots enable the use of higher end video cards, and ATI CrossFireX technology is fully supported to allow multiple video cards to be used together for graphics processing. Up to 16 GB of DDR3 memory can be used with this board.
