I feel similarly when I bought the R9 380 for 230 euros (new) from my local hardware retailer, when I got it it had fan issues for a month before AMD fixed it in the drivers, and even then the thing would downclock like crazy all the time and made some poorly optimized games macro-stutter. I thought the raw power of Red team was going to win over the GTX 960 which was cheaper and ran all games smooth at my monitors resolution.
I was always running an nVidia card since the Geforce 2 MX, from there it goes to 7200GS and then finally I got a good mid-range card for the first time in my whole life, it was the GTX 460 768MB in 2011 (for 100 pounds) which pretty was solid for 3 years before I sold it off and went looking for my next big jump in performance. (Most people probably think the GTX 460 is a damn dinosaur now, but hey it plays some recent ports from Square Enix at 1080p60FPS! Namely FFXIII)
Found a Gigabyte GTX 660 2GB last year for (for 100 euros) which doubled the performance in most games and I could finally play Skyrim w/ heavy graphical mods, but it it didn't have enough power even when OC'd to GTX 660Ti levels.
So in my mind the logical choice was which mid-range GPU to pick for 2016, should I keep the GPU that I spent money well on for once, or try to find an upgrade that might satisfy the ability to play heavily modded games without frame drops. I researched quite a bit before making the conclusion that on average the Red team was faster in most games so I began using the R9 380. Which is... decent, but for 230 euros a 20% FPS increase was worth it? Hell no.
But with AMD making their drivers really awesome nowadays (and they better keep at it) I think their cards hold up longer ever since the 7000 series came out. 28nm had a good run but overstayed it's welcome IMO.
I want to address something though, there's some FUD going around that nVidia is either dropping support for their GPU's really fast once a new generation comes out, or they deliberately are gimping their own GPU's since Maxwell architecture came out. The R9 280X/380 are now gnawing at GTX 780's heels in certain games, AMD hasn't made big changes since Pitcairn I think.
Though most GPU's start to really shine when OC'd. You can gain about 10 extra FPS from OC'ing a 750Ti. Which is impressive by my standards.
Anyway, I think the Nano really good, but for that kind of money... Ehhh. It seems like the software/games don't really take advantage of AMD GPU's. I still wish my old DX9 and DX11 titles had multi-thread for AMD GPU's, but Red team wussed out on better DX11 support for some reason, don't remember why.
Maybe I should try and sell the R9 380 and get the R9 480 which will have DX12_1 support when current Tonga GPU's have only 12_0. But the prices in my country are scary. You're expected to pay over 250 euros for a brand new mid-range GPU. Though in general the prices of newly released GPU's have been rising have they not?
There's just something about Radeon GPU's that makes me think they are being held back! I hate this feeling. It's the first time I've ever owned a Radeon card, and the experience in the beginning wasn't the best, but now I am enjoying the gaming bliss after a sequence of entry and mid-range cards not being able to run at 60 FPS for a modded game.
All in all, I believe I made the right choice in the end. I can OC my Gigabyte R9 380 G1 Gaming to 1200MHz rock-solid. Which brings it in terms of performance to about R9 380X levels. Which quite frankly should make this card last another 2-3 years before being replaced. Let's be fair, it is going to happen because I'm waiting for Elder Scrolls VI, Skywind, FF7 Remake and Resident Evil 2 Remake.
Sorry for not having tl;dr, I suck at making concise sentences.
