You know I too stuck with AMD through the FX "saga" I actually had 3 of them between 2 different PC's. FX8320 - FX8350 and FX9590, I've built few PC's for my friends with Phenom II X2 - X4 - FX and now Ryzen CPU's even my wife is running a 3700X and I had the 2700X and then 5800X I basically banned Intel for almost 10 years and nVidia for 7 but eventually you have to stop holding a grudge

I got the i9 because it was hard not to for £409 I will keep it for a year or two and will go back to AMD for the next many years
Yeah, your experience sounds similar to mine. I only ever had the FX-8350 but I started my AMD saga with a Phenom II X4 940. Then I bought a 990FX motherboard in anticipation of Bulldozer. Bulldozer was awful so I didn't touch it but I still had the 990FX motherboard and 16GB of DDR3.
I took my Phenom II X4 940, the motherboard and 8GB of DDR2, added an XFX Radeon HD 6450 to it, threw it into a case with a new PSU and 1TB HDD. I gave it to my mother (she still uses it to this day and is still happy with it) and bought a Phenom II X4 965. My craptop at the time had a Llano-based A8-3500M which I consider to be one of the best purchases that I have ever made.
When the FX-8350 came out, the performance difference was enough for me to upgrade and because Tiger Direct screwed up on one of their sales, I got it for $170CAD. After that, I got an R7-1700 and now have n R5-3600X. My current craptop has an R5-3500U because, in the long-term, I prefer having a Quad-Core CPU with SMT rather than a Hexa-Core CPU without SMT. Eight threads vs. six threads, even if they're slower. I don't do anything heavy on my craptop anyway. That's what my desktop is for.
My grudge towards Intel is based on their entire history. I started using PCs in 1984 and built my first in 1988. Intel turned evil when they first released their 32-bit 80386DX-16. To date, they have
never won a court case against AMD, having lost
every single one. That means that Intel was
always the one who was behaving badly. Intel's sandbagging has cost us dearly with regard to technological advancement.
See if you can wrap your mind around this: Intel's slowing of tech advancement, based completely on their greed, may have made it impossible to discover the secret of immortality in your lifetime. We are on the cusp of that discovery and if that's true, the greed of Intel and everyone who enabled their practices, has literally killed you. Another, equally dark scenario is that you could die from an illness just a year or two before a cure is found simply because the amount of computational power that we have is a few generations behind what it could have been. Even if that's not the case for you, it will be the case for someone else and it demonstrates just how critical the speed of our technological advancement is. It demonstrates just how callous Intel had become simply because of their psychopathic corporate greed.
When AMD's market share reaches 50%, or if AMD tries some Intel-like crap against consumers,
then I would consider getting another Intel CPU (It would be the first one since my Core2Duo). That's how you make a market healthy, not by jumping ship the second that the bad actor offers you a slightly better deal. The market as it is right now is
not healthy. Intel is still a domineering giant and AMD is still an ant in comparison. We need AMD to grow and Intel to shrink until they're at least similar in size. We also need VIA to step-up and re-enter the consumer market and I'm optimistic about that because they're getting a craptonne of money because the Chinese government is a major customer of theirs.
The PC market has become very sick over the years because every time a player is forced out, it has a devastating effect to the industry for several reasons. One is market collusion is much easier with fewer players, whether or not it is a result of illegal co-operation/"price-fixing" (AMD pricing the RX 6000 based on nVidia's pricing of RTX 3000 is a good example of non-cooperational collusion). Another is a reduction of innovation because fewer competitors will innovate less than more.
The market was much healthier with names like Quantum, Kalok, Micropolis, Maxtor, Orchid, CirrusLogic, S3, Oak Technologies, Diamond, Matrox, Zoltrix, Cyrix, VIA, etc.
In fact, the whole industry was just better when they were around.
