I have a 5600X with a 3080i and run triple 1440s. I turn some settings down in most games actually and have a bit more powerful GPU, but I would still recommend 1440 for your over 1080. Some people will say 32 is too big for 1080 up close like we use them. However, I personally still think they still look great at 32" and I don't see individual pixels on a 32" 1080 like some people say they can. The bigger thing is that you can always run them at 1080 for ACC if you want to but then use them in 1440 for other games if you do go with 1440 monitors. It gives you flexibility in the future if you do ever upgrade from the 3070. I say just bite the bullet now and pay the little bit extra they cost but then don't worry about them for a while. If you buy 1080 now, you will probably immediately start wondering how good things would look at 1440.
