I'll date myself. I had a Radeon 7200 (non-AIO). It was much better than the Nvidia RIVA TNT2. I up/downgraded to the dreaded MX 440, which caused artifacts. Turns out the computer only supported PCI and not AGP. Sent that back and got an AGP machine with a Radeon 9000. Mid-graded to a 9600, which was modestly better. From there I wanted to get an X800 or X850, but the AGP variant was rarer than the dodo, so I decided to build for the first time. Got a nice X1950XT right around the time multi-core CPUs came out. That golden era lasted until the fan went bust and then I got an HD4850.
Looking back, I was always rooting for Team ATI, not AMD.
