I'm considering upgrading my gaming PC from a 2080 Super to a 5070ti, but I'm worried about whether my i9-9900k will bottleneck the performance. I mainly play Call of Duty and want to know if I need to upgrade my CPU to get the most out of the new GPU. Just to give you a bit more context, here are my other specs: 32GB of GSkill Ripjaw 3600MHz DDR4 RAM, a Z390 AORUS Pro WiFi motherboard, and a Corsair 850W PSU.

Yeah, there's a good chance you'll see a bottleneck with a six-generation old CPU. Ideally, you want to keep your GPU and CPU about two generations apart for the best performance balance.
Yes, you might experience some bottlenecking with the 5070ti and your current i9-9900k setup. A faster CPU would definitely help you unlock the full potential of that GPU, but even so, it’s still a solid upgrade over what you have right now!
You should check out a bottleneck calculator with your specific games and resolution. I recently paired a 5090 with an i7-12700 and the only bottleneck I’ve hit is in one specific game—everything else runs smoothly!
Thanks for the tip! I'll take a look at that.
But honestly, don’t rely too much on those calculators—they can be misleading. Bottlenecking depends on a lot of factors like your game and resolution. Just keep in mind that some bottleneck is always going to be there, and it shifts between components.

That makes sense. Thank you!
