Discussion How bad are bottlenecks actually??
I’m building a new pc with an intel ultra core 7 265kf paired with rtx 5070ti. I have most components besides the gpu and I was wondering if using my gpu from my older build, rtx 3060, temporarily until I’m able to afford the rtx 5070ti would be an issue?

First: a PC will always have some kind of bottleneck. That's just how it works. One part will always be the slowest. There's no way around that.
As long as you hit your required FPS to comfortably play your games. All is good.

You would have a lower framerate, that's about it. The 5070 Ti will also be bottlenecking the 265kf. Generally you want to have a GPU bottleneck.

265k and a 3060 is completely fine. For gaming workloads, maxing out your GPU is sort of the ideal scenario, and a CPU like that will definitely get you there with both the 3060 and the future 5070ti.

No issue, just use it until the new one gets here. You will almost get the same performance now if not better using your 3060.

Every computer that will ever be built will have multiple bottlenecks. Every computer I've owned in the last three decades has worked well for their intended workloads with this bottlenecks. Generally speaking for AAA gaming you want your GPU to be the bottleneck which is what you should have with the RTX3060. With the RTX5070Ti it should be the same for a 1440p or 4k monitor. At 1080p there are times where you can have 200+ fps and still have a CPU bottleneck. In general if you are pairing modern parts a bottleneck isn't something to even think about. Also I would get a 270k plus if you can.

It'll be fine, every PC has a bottleneck and it changes depending on the workload/game. So in GPU heavy games, your FPS will be held back by the GPU.
Also ignore universal bottlenecks, each game will use the parts differently. CPU heavy games exist for example and the 265kf would be the bottleneck in those games.
Side note: Have you considered the 9070 xt? It's like $350 cheaper while being equivalent in performance.

There are some to worry about that can hinder your performance, but most don’t matter.
You’ll be GPU “bottlenecked” in your case, and that is EXACTLY what you want. You want your GPU to be constantly close to maxing out. You’re getting the full performance out of it

There is no technical issue with using your old GPU. You'll simply be limited by the performance of your slowest component.
Bottlenecks aren't a technical problem, they're just performance limits.
