What WoW Shadowlands settings will this PC be able to run WoW Shadowlands at?

I wouldn’t really base a purchase decision on RTX - it’s better now than it used to be but its still an immature technology with limited implementation.

Look at Kodiak’s results for RTX, pay less attention to the performance since 3000 series should be better, but look at the visual differences and ask yourself if you think it’s worth it to you to consider.
