Best Custom Gaming PC Build for $300: Full Specs and Performance Guide

Last Updated: 24th May 2017

Obviously if you’re looking to assemble the best gaming PC build for $300 you can’t expect anything too powerful, but if you’re smart about your component selections it’s definitely feasible to get a reliable rig that’ll handle 1080p gaming fairly well, and real smooth performance if you either turn down the graphical settings or play in the older 720p resolution (which doesn’t look that bad really).

As well as a decent full HD experience with most games, if you game in 720p or you plan on running mostly older (or indie) titles then this little rig could be all you need to put a smile on your face. The star components of the best gaming PC for $300 is the cost-effective AMD Radeon RX 460 graphics card and the Intel G4560 processor which both represent excellent bang for your buck for builders on a super-tight budget.

The RX 460 is an obvious choice in the sub 100 dollar GPU category as explained in our Best Graphics Cards series, with no competing card from Nvidia really coming close for the price. Note that we’re recommending the 2GB version, but there is a 4GB version of the card. Performance differences between the 2 versions is too minor to really matter, and since our budget is only 300 dollars we want to cut costs wherever possible hence why we’ve opted for the 2GB.

As for the Intel G4560, it’s also a clear pick in its price category at the moment and really packs a punch for little monetary investment with its very decent 3.5 GHz clock speed, 3MB of cache, and dual-channel DDR4 memory controller, and 16 lanes of 3rd-gen PCI-E. Don’t worry if that sounds like mumbo jumbo, all you need to know is the G4560 is hands down one of the best budget CPUs of all time.

For your main board we’ve gone for a respectable microATX Gigabyte motherboard in the GA-H110M-A which will serve this budget build well – just don’t expect any fancy features. As for memory you have 4GB of DDR4 RAM from the ever-reliable Crucial which is still plenty for gaming in this day and age believe it or not.

To round off this little gem of a machine we have a decent quality 500 watt power supply, mini Rosewill tower that doesn’t offer much space but good enough for our needs, and a 320GB traditional hard disk (feel free to go bigger if you need).
