Motherboard Information

The choice of motherboard can be one of the most difficult decisions when building a custom computer, but because of the effect it has on the rest of the build process we present it first. There has always been a debate over whether Intel or AMD is the best CPU choice in different applications, and the selection of a motherboard determines which processors will be available to pick from; choices over memory type and other related things add to the confusion. Puget Custom Computers has many hardware articles that can help you get up to speed, and by taking the time to give them a look you can make a much more informed decision. In the event that you are uncertain, don't hesitate to contact us.

All of our motherboards have built in LAN support. Motherboards often have other built-in features as well, including USB, Firewire, and RAID controllers. Each of the desktop motherboards listed below has full audio support, and in some cases even 6-channel or 8-channel sound! Make sure to become familiar with what features your motherboard has so you don't waste any money adding controller cards for features you already have!
