The best feature of this CPU from AMD is that it comes with an onboard GPU in the form of the Radeon Vega 8. While the onboard graphics will not give you the power of a stand-alone card, this is going to be plenty to run a lot of great games.

Is $300 enough to build a good gaming PC?

The honest answer is no. With such a tight budget you’ll be using an integrated graphics card instead of a dedicated graphics card, which will limit the games you can play. Alongside this you have a small storage capacity, so won’t be able to play games that require lots of storage. This is an entry level gaming PC so you can play some basic games, but you won’t be able to play AAA games without a dedicated GPU.

Will this budget gaming PC be enough for business work?

Yes. This $300 cheap gaming PC will be enough to handle business work and emails etc. You can browse the internet and watch movies, but it’ll struggle to handle gaming. You’ll need to make future upgrades to expand this gaming rig into something that can handle games on low settings, medium settings or even high settings with smooth gameplay.

PC gaming is not a cheap hobby. You cant do alot with a gaming setup that doesn’t have all the components you need. I recommend you upgrade the power supply unit, get a dedicated graphics solution and look for additional storage, preferably SSD storage.

Things to consider before getting a gaming PC under 300

There are some hidden costs when building your own PC compared to a prebuilt gaming PC. Things such as the operating system, which vary and aren’t all the same price, but can add costs to your build. Also PC games can be ran on this system with some overclocking, but most games won’t start. If you want to overclock you will need to upgrade the CPU cooler. Modern games struggle on an affordable PC build, so look to expand your budget.

This entry level PC build also doesn’t include a gaming keyboard, gaming mouse, additional fans, SATA cables or more storage.

What games can this gaming PC play?

It will struggle to play any eSports titles or run games that are demanding. It can with some light overclocking play some basic games such as:

  • Rocket League
  • Counter Strike Global Offensive

You won’t get a good gaming experience trying high end gaming, but you can play on the lower end with this custom build. This custom PC can also play most web based games such as Runescape.
