Doesn't matter how clued up the enthusiasts are, if they recently paid £550+ for an outgoing card, many are likely to be biased.
I remember reading "but if the 980 TI is overclocked" but when it's convienient people forget the new card can be overclocking and also overclocking isn't quite the same as out of the box performance either.
It's obvious new tech performance even if the paper FPS is the same as an outgoing product, it's going to be a much better all-round product than some old 1.5 to 2 year old tech.
Bingo.
There is lots of bias on this forum. Luckily it is easy to filter and can be half the fun anyway
