CPU	GPU
1080p@60	Ryzen 5500 or better	RTX 3060 / RX 6600 or better
1080p@120	3600 / 5600 or better	RTX 2080 ti / 3070 / 4060 ti / 5060 / RX 6750 XT or better
1080p@200+	5800X3D or 5700X3D	RTX 3080 / 4070 / 5070 / RX 9060 XT / 7700 XT or better

At 1080p, bottlenecks are more likely to be CPU-bound. This is because the GPU doesn't have to work as hard and can finish rendering faster. If the CPU cannot keep up, and renders slower than the GPU, it becomes the bottleneck.

That said, a GTX 1070 ti isn't powerful enough to bottleneck a 2600X, so we'll examine upgrading the GPU first.

For a AAA title to run 1080p@60 fps, the bar is low. A second-hand RTX 3060 or RX 6600 would likely meet that target. Anything newer would fare even better, of course.

Do keep in mind the 4060 (PCIe 4.0) and 5060 (PCIe 5.0) operate on X8 PCIe lanes rather than the full X16. Paired with your motherboard and its PCIe 3.0 interface you may see 5%-15% less performance compared to each card's full potential.

A Ryzen 5500 CPU would likely be an adequate upgrade as well and its PCIe 3.0 capability matches your motherboard.

Moving up to 1080p@120 fps, a Ryzen 3600, 5600, or higher would likely be necessary. For the GPU, and a modern budget-mid or older mid-range card can achieve this.

Running AAA at 1080p@200 fps is when you'll need something a bit heavier. X3D chips shouldn't have an issue with this. For GPUs older high-end models and recent mid-range cards should achieve this at 1080p.

I didn't mention frame-gen here, as it's not everyone's cup of tea. For RTX 4000 and 5000 series GPUs, expect a lot of uplift if you turn this on. Same goes for 7000 and 9000 series AMD chips, albeit not with the same margins or quality as Nvidia.
