I had a quick view at this post : https://www.reddit.com/r/radeon/comments/157qa6c/rx_6600_or_rx_6700_xt_for_1080p/

It seems to me that 6700xt is much stronger than 6600. More expensive, too. Personally, I would pay some extra money 6700xt, but it depends on OP’s budget and game preference.

I’d suggest OP to consider several factors:

1. Is the game you’re playing CPU-intensive? aka Will your 3600X be the bottleneck if you have a powerful GPU?
2. Do you have a 4K/1440p monitor?

I would definitely pay for the game Concord, just for its brand.

If the sub title is Sony Flight Simulator

At least 90% of the memes and jokes are unrelated to the game, just no brain copy paste. That’s really annoying.

I like game-related memes, but they’re really hard to find now

I also use Resilio Sync. It’s not open source software, but it’s self-hosted https://www.resilio.com/

There are also open source sync services, like nextcloud or syncthing
