Is it Worth Upgrading from an 14600KF to a 9800X3D for Gaming?

If that price for the CPU and motherboard is accurate, go for it! You could sell your old parts for a decent price. Just keep in mind that unless you're playing games that rely heavily on the CPU, the differences might not be very noticeable. Plus, using something like DLSS 4.5 could give you even better results in a lot of games.

Honestly, I’d recommend saving your cash. If you don’t have a noticeable bottleneck, upgrading just isn’t worth it right now. Stick with what you have unless you really feel the need to upgrade.

I usually advise against this kind of upgrade unless you're hitting a bottleneck. If it’s CPU-heavy games you love, then sure, but if you're not facing those issues, it’s probably pointless.

Before you rush into an upgrade, think about whether your 14600KF is actually bottlenecking your GPU. If you're playing CPU-intensive games like Crusader Kings 3 or Cities: Skylines, then the upgrade might be a good call. But if your current setup is running fine, especially at your resolution, you might not see much benefit.

Be cautious about that 300 EUR price—it seems a bit too good to be true for the 9800X3D. In Europe, it's more like 400 EUR for the CPU alone, and don't forget the costs for a decent motherboard. Also, ensure you know which motherboard you're getting; this upgrade isn't as simple as it looks. Consider whether a gain of 10-15% in performance is actually worth the extra expense you're facing.
