Many people still think RTX is too unmature / too slow to be worth it yet.
Many also think it's worth it, and fast considering. being able to run DXR in modern very great looking games, at 1440p or even higher, at frame-rates above AAA titles on consoles is quite acceptable. The only thing that is a real problem is price, so far. While that has gotten better, i still think prices are too high. No one would mind a 2080Ti at more reasonable prices, say whatever you want about RTX, but i personally think nvidia created a GPU with true rasterization performance boost over pascal, with the addition of RT hardware amongst other things.
Next year is going to be interesting with RTX 3000, AMD's navi2.0, and possibly Intel gpu's competing with each other.
