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.

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.
