Should I Upgrade My CPU Now or Wait for a New Build?

Upgrading your CPU is definitely a good idea, but remember that it might also require a new motherboard and potentially new RAM if you want to switch to DDR5. This could push your budget a bit beyond 250€. It's important to consider that the LGA1151 socket is discontinued, which means it could be tough finding supported Intel CPUs. Looking for used options online could help you stay within budget. Plus, you might still be fine sticking with your GTX 1080 for a bit longer, especially with what you're currently playing.

Your i5-7600K is one of the best options you can get for your current setup, but any CPU upgrade is likely to require a new motherboard. If you're aiming for better performance now, consider going for an AM5 motherboard with a low-end AMD chip that supports future upgrades. Having a setup that accommodates PCI-E 5.0 will help with future-proofing your build.

For around 200€, you might snag a Ryzen 5 5600X and some budget RAM along with a cheap motherboard. This change would definitely carry you for another couple of years. However, if you're gaming on a 2K monitor, a better GPU might be the better upgrade route for now. Just save up for a full build when GTA 6 drops! That said, if your current system isn't meeting your needs, then a minor upgrade makes perfect sense.

You can look into getting a used 7700K, which should be a decent upgrade without breaking the bank. Just double-check that it's compatible with your current setup. It's a solid performance boost and might help bridge the gap until you're ready to invest in a full upgrade.

It sounds tempting to upgrade now, but if you're considering dropping around 250€, you might be better off just saving for a full new rig, especially if plans include high-demand games in the future. Keep an eye on where you want your performance to be in the long run; it might be worth it to save up a bit longer.
