I was team Red for a while.
The HD5850 was a nice piece of kit but I believe it got outgunned by Crysis 2 and BF3 and the likes. At which point I bought a new GPU.
That new GPU was the HD7950 and it caused all sorts of problems. Frame skipping, screen tearing the whole shebang. AMD promised driver fixes of which few materialized.
I watched my buddies with Nvidia cards happily play the latest releases, while I was waiting for AMD to release another 'hot fix' so a new game would actually boot or not be stuck at 20fps.
I was so let down by AMD that I bought a 980 Ti when it launched along with a 4790k build.
About a year ago I dug up the HD7950 for the office PC of a co-worker and it crapped out within a month.
The 980 Ti serves me well for about 4 years now. BFV is the first game I can't run on Ultra on 1440p.
So now I'm looking at replacements. The 2080 Ti is expensive but it could potentially end my performance woes for another 4 years.
However, the 2070 Super seems very decent if the pricing is as promised. AMD is just not worth taking the risk anymore.
A GPU that runs at 90 degrees with fluctuating voltages and broken fan control drivers that's a yikes from me.
