the 20-- series are the current series. they are seperated by their price point. 2080 is super expensive, 2070 is up there, 2060 is around 300ish, and usually theres a 50 model too for like 200 ish but there isn't one this time
BUT
nvidia is stupid and decided to add "SUPER" to them. so now theres the 2060 SUPER and 2070 SUPER, where the 2060 SUPER is as fast as the old 2070 and the new 2070 SUPER is about as good as the 2080, but their price point division is the same
THEN THERES THE TI MODELS AND UGGGGHH
look just get a 2060 super or 2070 super, which ever you can afford and dont think about getting the "new" one cuz its dumb. its all dumb.
My biggest worry is that a new gen is coming up and I'm worried if I drop a lot of money I'm going to not be able to play new games in a year or 2.
I'm still probably going to get a PS5 even if I get a gaming PC. I'm using my gaming PC for "western" games
