No, a new GPU won't cause your CPU to bottleneck unless it's significantly slower than your current CPU.

Hello, I was checking out an upgrade for my GPU when the latest NVIDIA models came out. I wanted to switch from a 1080 to a 3080 but wasn’t sure if my CPU was holding things back. My current CPU is an i5-8600K. Should I consider upgrading it to avoid a bottleneck?
The RAM has one negative, which might mean your CPU wouldn't work well with the 3080.
Well coffee lake gains from quicker RAM, so an upgrade would be beneficial. For the CPU, gaming performance is still solid with an 8600k, but evaluate its amperage and stability when paired with the 3080. It shouldn't be too much of a problem, but if you're considering an upgrade, a used 8700k could be a great choice. Just wait for amperage to stabilize and assess its impact before deciding.
Games now focus more on multicore optimization and will keep improving. However, for the same cost, upgrading to an RTX 3080 gives better FPS than moving from an i9-10900K with a new motherboard. But an i5-8600K 6c/6t won’t perform well with an RTX 3080—it already struggles with an RTX 2080 Ti. If you can only afford the RTX 3080, go for it; check reviews when it launches or preorder soon if possible. And if you also want a CPU upgrade, wait for Intel 11th gen or Ryzen 4000.
RAM boosts gaming performance by allowing faster data access, which helps the game run smoother and more responsively. Even with a large amount like 16GB, it only benefits games that require high memory usage, so you might not notice the difference unless you're playing demanding titles.
Consider upgrading to the RTX 3080. When Ryzen 4000 or Intel 11th generation models are released, evaluate the FPS improvement over your i5-8600K in the desired settings and resolution. Weigh the investment against the benefits. Avoid an Intel 10th gen processor since it lacks PCIe 4 support. Skip the Ryzen 3000 and wait for the 4000 release, which should arrive soon.
For RAM, opt for speeds around 3200 MHz—it will noticeably boost your FPS, especially given your current 1000 MHz setup. Check benchmarks like this one to see the impact on game performance.
