The Ryzen 9 3900X is one of the most powerful CPUs available right now in 2020, and is perfect for those that want to start getting into proper multithreaded applications or enthusiast-level gaming.
However, getting a high-quality CPU is only the first step in building your perfect setup. To be able to utilize your CPU to its fullest extent, you need a suitably excellent GPU to go along with it – to prevent any potential bottlenecking.
It is no good just picking up any old GPU, or even the most expensive one, as they are all independently useful for different things. You might be looking for practical uses for your setups, such as video editing and rendering, or you just want to play gaming as hardcore as you.
Whatever your needs are, here is a helpful guide for what GPUs to get so that your final Ryzen 9 3900X setup is perfectly balanced for your needs.
Best Graphics Cards for Ryzen 9 3900X – My Recommendations
Best Workstation GPU for Ryzen 9 3900X Builds
If you are planning on using your PC for primarily productive reasons, whether that be workflow or even some light video editing, you still need a decent quality GPU to be able to take advantage of your CPU’s power.
While you could certainly go for a more expensive option, one of the best things to get for yourself would be a GTX 1660 Super – with our AIB recommendation being the ASUS ROG Strix 1660 Super.
With cooler and quieter running with 0db technology and excellent overclocking capabilities, this 1875 MHz base clock card is an excellent compromise point between most other budget cards and still being able to run everything that you need.
While it might struggle a little bit with some of the more advanced graphical rendering, such as intense animations, it is perfectly suited to rendering, editing, and even some light gaming if you find yourself itching to put your GPU through its paces in tandem with the Ryzen 9 3900X.
Best Light-Gaming GPU for Ryzen 9 3900X Builds
Casual gaming might get spurned by some of the more diehard purists among the computer world, but it has a valid place. There are so many games and genres, like Grand Strategy or Puzzle games, that do not require incredibly powerful GPUs to be able to enjoy them properly.
For those with a preference for lighter games, then the Sapphire RX 5700 XT Pulse is perfect for the Ryzen 9 3900X – our favourite aftermarket RX 5700 XT card. This GPU has a very respectable base clock of 1770 MHz and a decent potential for boost. It is almost specifically designed to work well with AMD CPUs, and is capable of running even high-intensity games at 144HZ and 1440p without a struggle.
However, for those that want to game only lightly and casually, with only the occasional foray into more graphics-heavy games, then this is the GPU for you. It is not only still powerful enough to do almost anything you need with the Ryzen 9 3900X, but it manages to not break the bank at the same time.
Best GPU for Ryzen 3900X Enthusiast Gaming PC Builds
To really get the most out of your Ryzen 3900X, you need to stretch your budget to include the RTX 2080 Ti. While it is unattainable for most, this new flagship GPU is absolutely mind blowing its performance.
With 11gb of incredibly fast GDDR6 memory and a clock speed of 1546 MHz, this insanely potent GPU is pricey for a reason. The key evolution of this GPU from older RTX models is its massively increased memory bandwidth; 616 GB/s of bandwidth means that this GPU does anything and everything pretty much instantly – no more waiting for load times or struggling when under heavy load.
This same great Turing architecture and NVidia RTX design, unfortunately, does require a lot of power, needing 250W just to run, but if you can fit it onto your motherboard, there is no reason not to invest in your PC’s future with this behemoth of a GPU card.
In terms of AIB cards, most models all perform near identical so we would recommend to get hold of the cheapest one you can find, and you certainly won’t be disappointed with picking this for your Ryzen 9 3900X gaming PC build!
