We had the Riva TNT2 in our family computer, so that was fun to see that again, I think it was paired with an AMD K6-2 chip.
One day one of my friends from school wanted to optimize airflow in our computer, and re-did the cabling, but he managed to block the CPU-fan from spinning. I am not sure how, but we didn't realise it for a couple of months.
When I got my own PC, it had an AMD Barton chip, and it allowed me to play Half-Life 2.
