GIGABYTE has taken their already very successful P55A-UD6 board and improved upon it. They added a NF200 chip to allow for extra PCI Express lanes and the ability to do 3-way SLI or Crossfire on this board. The second feature they include is the Hybrid Silent-Pipe accessory which cools the chips that run notoriously hot by putting a heatpipe module to transfer the heat. The other improvements include 10 SATA ports, and the USB 3.0/SATA 3.0 support from the other board. This board offers the performance and features you want from a P55 motherboard.
