You're just being pedantic
I could have related it to any number of things... a tv, a microwave oven, a washing machine. I chose a car because generally people don't change perfectly good cars because they NEED to.
My point was that some people are claiming they NEED to buy one of these new cards, like the one they have at the moment stopped working at 5pm BST on 20th Aug 2018.
What I'm sure they mean is they WANT a new card. For bragging rights, snobbery, willy waving or whatever reason. Claiming it's for better performance is a guess because we don't know those figures yet (for certain).
Anyway, that was my point, albeit exaggerated for effect. Just because something new comes along, doesn't suddenly mean they have to buy it. Especially people with 1080ti and the other high end stuff, they still work fine
I also get the feeling the 20 series will get a price drop as soon as the remaining 10s are gone. Probably before Xmas. Unless crazed groupies keep throwing their panties (and wallets) at JSH
