I'm typing this on a Bulldozer system. It is still fine for what I need it for - mostly compiling software, and provided a lot more cores than the equivalent Intel CPU at the same price point.
Nobody's saying they were unusable. But like--I do video production and was pricing out my first live video mixer around that time. I was ready to throw down for a Bulldozer build immediately because of how wide the processor was and had to do the proverbial "hard pull up away from the mountainside" because of how bad the throughput was.
Instead, ended up going i7-875K -> i5-3570K -> Ryzen 1600 -> Ryzen 3700X (probably, this year). So like, I'm glad to see AMD back in the game, but Bulldozer was pretty rough.
I'm still using mine for gaming daily, obviously it's not high end, but it was $99 like...9 years ago? I don't remember when actually. I've been computing since I was young and it's the best value I've ever purchased. I can still do just about anything I want to right now.
