I'm building a new PC because my old 1080ti finally kicked the bucket after 8 years! Previously, I had 32GB of Corsair Vengeance RGB Pro SL memory at 3600 MHz, and I just bought another kit to bump it up to 64GB. I was planning to use this with a 14900KF processor and a B760 motherboard. However, I've realized that I could potentially sell the RAM and upgrade to 32GB of DDR5 with a Z790 motherboard for a similar cost. Given that I already own the DDR4 kit and RAM prices are inflated, I'm pondering whether it would be worth sacrificing some capacity for faster memory and a better motherboard. Does anyone have insights on whether this is a smart choice?

If you're just gaming, 32GB DDR5 will likely be the better route for personal use. Unless you're into heavy video work or tasks that need the extra capacity, DDR5 is a solid way to go.
For gaming, 32GB is typically more than enough for quite some time. If you're mostly gaming, stick with that.
It really depends on the game. I'm pushing my PC hard with BeamNG, and 32GB feels tight for me; I hit almost 29GB usage with it.
There's no real need for 64GB unless you have specific intensive workloads. In your case, 32GB of DDR5 would likely serve you better performance-wise with that new setup.
But it makes me feel like I need more. Haha, sometimes it's about the peace of mind!
It really comes down to your needs. If you don't need tons of RAM, go for the DDR5 for better performance. But if you want to be able to run everything smoothly, keeping the 64GB DDR4 could also be beneficial. Plus, I’d be curious why you chose the 14900KF for this build?
I got it on sale, and I'm going for a bit of a budget refresh.
I think you should sell your DDR4 and go for the DDR5! It'll help you keep up with the rising prices while getting a bit more performance. 64GB is nice, but not necessary unless you multitask heavily on various programs.
I feel you! I usually run a lot of things and hit around 25GB even before gaming. But considering what I do, 32GB should be okay for you too.

But don’t underestimate DDR4's capability in certain scenarios!
