I'll admit the price-to-performance of the RTX 2060, being %100 identical (not worse yay!) to the price-to-performance of the GTX 1060 along with Nvidia opening their cards to AMD's competing Freesync technology tickled my intestines a little bit to bite the bullet and build a rig, but the reasons to wait it out this year far outweigh the reasons not to.
RTX 20xx series is basically a refreshed GTX 10xx series with reflections in your games. The insignificance of Ray Tracing is only outshined by it's out-of-reach price. The technology wasn't available to game developers before or even when it was released, and the price is too much for gamers. It is basically by nincompoops, for fools and has absolutely nothing to do with gaming or gamers.
Each RTX card model is performing and priced equal to the next tier card in the previous generation, except the RTX 2060, again because it has the same price-to-performance as the GTX 1060. So the only reason to buy the RTX 2060 is because it's not worse than last generations cards as all the rest are.
Another reason to wait is the underwhelming Vega 7. It was designed for embedded applications first, games second. So I'll wait for a proper gaming card when they actually design one in the first place.
The most important reason to wait is to communicate your disapproval of the current state of the PC gaming industry. Everything they are doing is the exact opposite of what a gamer needs.
You want more performance for your dollar$? Why would you want that? check out the reflections in your game! Nice huh?
You want cooler hardware with lower TPD? wait wait, how about a ***kin disco ball on your desk!? Let's light it all up with RGB YAY! Let's RGB your headset and have a good laugh at ya suckers.
Wait for Nvidia's 7nm cards and for AMD's Navi cards.
Wait for Ryzen 3, sorry, Ryzen 3000. Corrected after the backlash. If only AMD cared as much as you guys do about their lost sales potential caused from the confusion.
9th Gen Intel is overpriced. Ryzen 1&2 IPC/single-core performance is not good for gaming.
Don't buy the crap they're trying to feed you.
