I built a pretty solid PC back in 2015, featuring a Z97 ASUS Sabertooth motherboard, an Intel i7 4790k CPU, an ASUS 980 Ti GPU, 16GB of DDR3 RAM, and two 2TB SSDs. Life got busy after having three kids, but now I'm ready to dive back into gaming. My question is whether I should just upgrade my GPU to something like a used 2080 Ti or 3080 Ti, or if I should go the whole nine yards and build a new setup. I'm not looking for top-of-the-line graphics, just something good enough to enjoy single-player games from around 2022 or older on my 1440p 144Hz monitor, ideally comparable to an Xbox Series X experience.

Honestly, your i7 4790k is still decent for older games, and the 980 Ti could even manage some 2022 titles at 1440p. If you're looking for a simple upgrade, get a newer GPU from the 20XX or 30XX series. Check out places like eBay or maybe local retailers for a good deal. You definitely shouldn't need to build a whole new system just yet!
I would recommend running some benchmarks to identify where your system is bottlenecking—likely the CPU or RAM since you’re on DDR3. That said, upgrading to a modern GPU like the 3070 could extend your system's life. If you need more cores for gaming, you might end up looking at a full build anyway.
Your setup should still be okay for games up to 2020. Just know that many newer games are starting to recommend at least 6-core CPUs, which might make a full upgrade necessary in the future. Play some older games and see how it performs; you may find it runs fine enough for your needs!
