I'm building a high-end PC with a 5090 and a 9950x3d processor, and I'm torn between two RAM kits. One option is a 32GB G.Skill Trident Z5 Royal Neo running at 6000MHz with CL28 from a local store, and the other is an unopened 64GB version of the same RAM from a reputable eBay seller, but it's $230 more. I want my build to be as future-proof as possible for an ultra-smooth gaming experience, especially since I primarily play Escape From Tarkov and other AAA titles on a 2K ultrawide monitor. I'm also curious if the 64GB RAM runs significantly hotter than 32GB. What do you all think—should I invest in the 64GB from eBay or play it safe with the 32GB from the store?

If you're not running heavy workloads like 3D rendering or complicated engineering software, then 32GB is probably more than enough for most tasks, unless you tend to have tons of browser tabs open. But with a system like yours, you might find that 64GB gives you peace of mind for the future.
Honestly, since you're already going for a 5090, why not just go for the 64GB? It seems like a solid investment for future-proofing, and you'll have the extra capacity for any heavy gaming or multitasking you might do down the line.
I've been using 32GB for a while and only maxed out during CPU intensive tasks like local AI training or heavily modded Minecraft. For regular gaming, like Fortnite on my 5090, I rarely hit the limit. So, while 32GB is sufficient for most, 64GB definitely gives you more breathing room. Plus, it shouldn't run significantly hotter than 32GB unless you're really pushing it.
If you're gaming and occasionally listening to music or running other apps, sticking with 64GB for the extra headroom seems smart. Even though it's from eBay, if the seller has solid feedback and it's unopened, it should be fine. Some tech YouTubers have mentioned potential compatibility issues with non-binary RAM, but if you're just gaming, that's likely not a huge concern.
