Why we chose these Cyber Monday PC deals

When choosing Cyber Monday PC deals to put together a build with, there are many factors to consider. Not only is it important that you're saving a good amount of money, but you also want to make sure that your parts are a good fit for each other so that you won't have any performance bottlenecks (you wouldn't want to pair a budget-tier CPU with a top-notch GPU, for example). On top of this, it's crucial to make sure that everything is compatible with the other components you're buying.

It is for these reasons that we've chosen the parts we have in this roundup. These components all offer excellent bang-for-your-buck value, and since they're all in roughly the same performance class, you won't have to worry about bottlenecking. Also, we've made sure that all the parts are compatible with the case, motherboard, and PSU we've recommended. Of course, the Cyber Monday deals themselves are also awesome, as everything is available for a significant discount.

Once you've snagged all these deals, the final step of the process will be to actually put the PC together. This should be easy to do since none of these components are particularly difficult to install, but if you've never built a desktop before, don't worry. Our in-depth guide on how to build your own PC the right way will walk you through the process with plenty of detailed instructions, tips, and photos.
