Since its release nearly two years ago, Nvidia's RTX 4090 is the fastest gaming GPU consumers can get their hands on. The GPU that offers Nvidia's fastest consumer-grade performance to date comes in multiple aftermarket trims as well as a Founders Edition that seems to be in perpetually short supply at its MSRP of $1700.
Why Is It Important To Pick Performance-Centric Hardware To Pair With The RTX 4090?
The RTX 4090, by virtue of its performance tier and the considerably large swathe of 24GB of GDDR6X VRAM it comes with, is considered an enthusiast-grade GPU that does more than just gaming, catering to a variety of productivity-based use cases such as video editing and AI. This makes what is a GPU that can easily fetch a sub-$2000 price tag for its highest-tier aftermarket models somewhat necessary to build around PC components to exact the most out of its performance potential with it routinely costing more than the rest of the entire builds it takes center stage in.
