I'm aiming for 1440p gaming at around 60 FPS with high settings in most games. I currently have a Core i9-12900K, an ASRock Z690-C motherboard, and 16GB of DDR4-3600 memory. My current GPU is an RTX 3080, and I'm considering upgrading to either an RTX 5080 or RTX 5070 Ti now, then replacing the motherboard, RAM, and CPU later—possibly with a bundle deal. I know 16GB of RAM isn't ideal anymore, but it hasn't caused problems for my current use. Would my existing CPU meaningfully bottleneck either GPU, especially at 1440p?

Your processor should be fine. I’m using a 11900K with an RTX 4080 and it still performs well, although the 12900K can run hot, so good cooling is important. If you want higher refresh-rate gaming later, the CPU limit matters more, but for 60 FPS it’s unlikely to hold you back.
A 5080 is faster, but whether it’s worth the extra money depends heavily on the current price difference. Some comparisons put it around 15–20% ahead of the 5070 Ti, while other game mixes can show a larger gap. For a 1440p high-settings build, the 5070 Ti is the more sensible value choice unless you specifically want maximum performance or more future-proofing.
At 1440p, the difference between the two cards probably won’t come from CPU bottlenecking with a 12900K. I’d choose based mostly on pricing and the performance you actually need. A 5070 Ti should already handle 1440p very well, while the 5080 gives more headroom but may not justify its higher price.
For a 60 FPS target, the 12900K should be perfectly capable with either card in almost every game. You might see a CPU limit in unusually demanding simulation or flight games, but that shouldn’t be a major concern for normal 1440p gaming. Make sure the RAM is running in dual-channel mode, though.
If you’re only targeting 60 FPS, the frame cap itself will usually be the limiting factor before your CPU becomes a serious problem. A 5070 Ti with 32GB of DDR4 would likely meet your goal in nearly all situations, and upgrading from 16GB would also help with newer games and multitasking.
That makes sense. I’m less worried about hitting exactly 60 FPS and more interested in keeping the option open for a 120Hz or 144Hz monitor later, so the extra GPU headroom could still be useful.
