I have a 3070 that I got recently, but I still have my old i7 7700K processor. I've been putting off my mobo/cpu upgrade, I wonder if I'll need to do that

Are there any apps for Lemmy that have a "hide read" feature? I had recently started using Sync for Reddit for that feature, because I like to be able to refresh and see all new posts instead of weeding through stuff I've already seen. Any tips would be appreciated!
