Gaming Performance

Right now, a $400 PC build like this has to use integrated graphics from the processor to save on money. The whole point of this build is to create a PC gaming foundation.

Then when the time is right and you’re able to afford a dedicated GPU then you’ll be able to have a pretty decent 1080p gaming build on your hands!

Even with the integrated Radeon Vega 8 graphics, you’ll still be able to have decent enough performance to be able to play many different titles.

You will have to downscale your resolution to 720p and play on some of the lower graphics settings without a dedicated GPU, but you will be able to achieve 40+ frames per second in most cases by tweaking the graphics settings in most games with Vega 8.

If you’re looking for a gaming PC build to upgrade in the future and you are okay with entry-level performance for now, then this would be the perfect build to start with.

How To Build This $400 Gaming PC

I’d highly recommend following something like the video guide below when it comes to putting this PC together. It’s a great guide and it is easy to follow!

There may be some parts that are different from this build in the video embedded below and that’s okay! If there is another part that you don’t understand then you should look through the manual of that part and/or look up other video tutorials as well.

If you find yourself having trouble understanding a certain part then you should always search for the specific part and how to install it on YouTube, there are plenty of videos out there showcasing how each part can be installed.

For example, if you aren’t sure how to install your solid state drive then simply search “How to install a solid state drive into PC” on YouTube and you’ll find plenty of material to follow.

Also, you don’t have to use the above case for your build!

You can use almost any other mid tower case if the above case isn’t your style. Feel free to browse the mid tower cases on Amazon and if you find one that you think you’d like to use, link it to me in the comments below and I’ll be able to let you know if it’d work or not.

After putting your rig together, you’ll need to install your operating system, drivers and other software. You’ll also need to get connected online.

There are a couple of posts here on the site that you should read up on if you need to know how to install your operating system as well as getting connected online.
