Is a GPU upgrade to the RTX 5070 Ti worthwhile for 4K gaming on an LG C5?

I have an MSI prebuilt that I bought a few years ago. Its current specs are an Intel Core i7-13700F, 64GB of DDR5-5600 memory, and an RTX 4060 Ti 16GB. I use a 42-inch LG C5 OLED TV as my main gaming display. The RTX 4060 Ti is currently handling my games acceptably, but I'm considering upgrading to an RTX 5070 Ti for better 4K performance and longer-term usefulness. The main complication is that I would also need to replace the prebuilt's power supply, so the upgrade would cost roughly $1,200 for the graphics card plus another $120 or so for the PSU. Would the difference be noticeable on this TV, and is the performance increase worth the extra cost?

I’d base the decision on the games and settings you use rather than upgrading just because the opportunity is there. If you’re playing 4K with demanding settings and want higher refresh rates, the upgrade makes sense. If you’re comfortable with the current performance, keep the 4060 Ti and upgrade later when prices improve. A 5070 Ti can be a great card around $830, but paying roughly $1,200 changes the value calculation completely.

The upgrade would be substantial at 4K, but whether it’s worth it depends on your current experience. If the 4060 Ti already gives you the frame rates and image quality you want, there’s no urgent reason to replace it. At around $1,200, though, a 5070 Ti becomes much harder to justify—especially since it can get close to the price of a higher-tier card. I’d wait for a better deal or compare prices with a used RTX 4080/4080 Super.

Your 42-inch OLED can absolutely show the difference. At 4K, a faster GPU can provide higher settings, better ray tracing performance, and smoother frame rates. The improvement will be most obvious in demanding games, not necessarily in every title. Your 13700F and 64GB of RAM are more than adequate, and replacing the PSU is a manageable job as long as you use a quality unit and replace every modular cable with the cables that come with the new PSU.

You could also consider AMD’s 9070 XT if the pricing is better. AMD graphics cards work perfectly fine with an Intel processor; the CPU and GPU brands do not need to match. The main tradeoff is that Nvidia may be preferable if you specifically care about ray tracing, DLSS, or certain creator and AI workloads. Compare actual prices rather than assuming the 5070 Ti is the best value.

MellowCactus47: That’s what I’m trying to figure out—I don’t want to spend over $1,300 unless the TV will make the improvement obvious. The 4060 Ti isn’t giving me problems right now; I’m mostly thinking ahead.
