Gears 5 is an absolute beast at 4K and requires an even more beast-like gaming PC to run it, with our Intel Core i7-8700K equipped rig with NVIDIA's finest Turing graphics cards in the GeForce RTX 2080 Ti and TITAN RTX the only cards capable of 4K at 60FPS. Nothing that AMD has on the market comes remotely close, with the Radeon RX 5700 XT offering 39FPS average at 4K versus 62FPS on the RTX 2080 Ti.
Not everyone wants to play, nor actually own a 4K gaming monitor -- with 2560x1440 a much more popular resolution, and a personal favorite of mine. At 1440p, every single graphics card we tested from the GeForce RTX 2060 and Radeon RX 5700 and up were capable of over 60FPS, with the RTX 2080 Ti topping out at 104FPS average.
With everything cranked up to Ultra bar a few settings like AA, you can enjoy stellar performance in a great-looking (and super-popular) game like Gears 5. However, if you want to truly crush your gaming rig into a fine dust then you will need to run Gears 5 at 8K -- or 7680x4320 which is 4x the pixels of 4K and 16x the pixels of 1080p. Truly insane stuff, and something I tested here -- Gears 5 benchmarked at 8K.
With all of the testing done, any of the new stack of graphics cards from both AMD and NVIDIA will offer great performance at 1080p and 1440p with over 60FPS on all of the cards above the RX 5700 and RTX 2060. But if you want to step into the realm of 4K with most details cranked to the max, you're going to need to side with Team Green.
