It might be early, but Black Friday desktop PC deals have begun. Some retailers have already launched early deals on everything from home office computers to gaming PCs to all-in-ones. What’s more, many retailers are offering price protection so you can make your purchase now and rest assured you’ll end up with the best price.

For prebuilt gaming desktops, a few companies are reliable and widely available. Dell's Alienware division produces solid if sometimes pricey PCs that have a fan following. Asus's Republic of Gamers line hits the midrange and high-end markets with good machines. Acer's Predator line is also good, and HP's Omen models have their adherents.

The only way you can beat the value, customizability, and power of a desktop is by dropping that price tag with a big old discount just in time for the holiday shopping season.
