Well, the amount of comments asking about payola is (not so astonishingly) quite high, so I don't need to say anything more about it.
But I have to chime about "the 4K experience". On my system, I would not be able to enjoy 4K except through the use of DSR: I don't have a 4K-capable monitor (#1 is a 1600x900/75Hz model, #2 is a repurposed 1366x768/75Hz HDTV), & it's been fine running R9 380 for my graphics. A GTX 1070TI/1080, let alone a 1080TI/Titan XP or an RTX 2070/2080, would be a complete & utter waste of my money...especially since a) the primary games I play on it (SC2, D3, Halo:CE, Fortnite, HBS's BattleTech, & occasionally BF4) are not photo-realistic enough to have any kind of benefit from ray-tracing (not to mention not even on the support list), b) I would see little to no visible improvement with the GPU but would see much more improvement if I were to spend $800 to $1,000 USD on a new CPU/motherboard/RAM (& wouldn't even need to spend that much, the cost of a discounted 1080/1080TI would give me a decent upgrade budget), & c) I would say that my PC's gaming usage maybe tops out at 10%; the rest of it is used for email, shopping/research, & by my wife to prepare presentations & reports for work (none of which would benefit from a GPU upgrade). I know I'm not in the "power gamer" category, & although I love games & gaming I know that between my system & the time I spend I'm not technically an "enthusiast"...but I AM a "mainstream" gamer. These RTX cards provide nothing for mainstream gamers like me...& from the information nVidia has provided, their 2050/2060 cards aren't going to have ray-tracing anyway (as apparently they'll be badged as GTX, not RTX).
So, yeah...if you have the kind of disposable income where you can drop as much on a new PC as you would for a down payment on a new car, and have the mindset of having to stay light-years ahead of the Joneses by always having the "bleeding edge" technology (& paying every year to get it)...then yes, by all means, go ahead & preorder as many RTX 2080s as you can get. Otherwise, you can safely ignore the "advice" from this article.
