6700XT vs 7800XT (First Build) (lemmy.world)

Hello, very simple question. I am doing my first build and about to order my parts, but I was wondering if the 7800XT is worth the leap and possible long-term gains over the 6700XT? I wanted to know personal experience from normal people, rather than a bunch of tech youtubers. Also if you use Linux, that would be quite helpful.

It's not just about how much RAM, it's about how big the memory bus is. The 6700XT has a 192-bit memory bus, and the 7800XT has a 256-bit memory bus. That means the RAM can work faster.

Probably why the 6700XT is matched by the 3060ti instead of the 3070; even though the 6700XT has 4GB more RAM, the 3060ti has a 256-bit memory bus.
