Nvidia’s RTX 4000 graphics cards have finally arrived, and the first GPU up for grabs is the flagship Founders Edition 4090 which released yesterday (at the time of writing). Reviewers all over the world have tested this GPU and put it up against some intense benchmarks, along with 4K games maxed out with Ray-Tracing and the new DLSS software enabled. The general consensus is that these cards are awesome, and despite being priced very high, you get what you pay for.

However, today is rather exciting because we can finally talk about all of the AIBs that we’ve had the chance to test from a variety of manufacturers. These cards sport brand new designs with some of the options offering liquid cooling, or a number of fans to aid with thermals. Others sport better clock speeds to give a performance boost. Today, we’re putting together a PC build that’s main feature is a Gigabyte RTX 4090 AORUS Master. This card has a bulky triple fan design with some RGB and crazy performance designed perfectly for high-end builds. We’ve paired it up with one of AMD’s latest Ryzen 7000 CPUs, the Ryzen 9 7900X, and some other insane components to give us the performance we need for an awesome 4K gaming PC!
