Will 2 year old motherboard cause a bottleneck in performance with the new GPU

Options

Looks like my son's 2 year old RTX 2070 Super Windforce 8GB 3X OC is going bad and will need to be sent in for warranty evaluation. Unfortunately, it leaves him without his gaming pc for several weeks or longer. He has decided that it would be easier to buy a new GPU for the time being and sell the old GPU when it comes back. He is considering a Gigabyte GeForce RTX 3080 Ti 12gb gaming OC. He will only be changing the case and GPU at this point but is wondering if the new motherboard will cause a bottleneck to the new GPU. The motherboard is a Asus TUF gaming X570 wifi ATX AM4. Current System includes:

ASUS Tuf Gaming X570 plus WiFi motherboard, AMD Ryzen 7 3700 cpu, Corsair H100i Liquid cpu cooler, 32GB G Skill F4-3600 RAM, Various Samsung SSD and Mvme drives. Current case is a Fractal Design Meshify C Mid Tower case, and 850 watt Corsair Gold PSU.

He does know that if he changes the GPU, he will have to change the case due to size of new GPU. His chosen case is a Corsair 5000x.

Thoughts ?

    No, the TUF Gaming X570 Plus WIFI is still a good board. The X570 is still current. The question you may really have here is if an older PCIe 3.0 board/CPU would bottleneck a 3080 Ti. And the answer to that question is no, or if it did by a miniscule amount. This isn't applicable, the board and Zen 2 CPU you have support PCIe 4.0, but here's an article on this from Puget Systems.

    The question you want to really ask here is will the Ryzen 7 3700 bottleneck the 3080 Ti. The answer is it depends on the resolution. At 1080P, yes, there will be a bottleneck, it will not be significant. The system is going to run great. At 4k the load is significantly higher on the GPU than the CPU and you wouldn't see a bottleneck.

    At 1440P there may be some bottleneck, but it wouldn't be significant. Even on at 1080P, you might see a 10-15% drop with the 3700, but it's still a 3080 Ti. You're not going to have any problems running games for a long time. I think it would be a difference between 230 FPS or 210.

    Keep in mind, that board is compatible with 5000 series Ryzen CPU's. You can update the BIOS and drop in a new CPU down the road.
