Until a couple months ago, I had a K6-2 550MHz system. I ran it with a Savage4 16MB card for most of the time I had it, but I also had a Radeon 32MB DDR card in there for it's last few weeks. Even though no socket7 boards support AGP4X, I did notice a speed and quality increase when playing games on the Radeon vs. the Savage4. The system ran every game I ever put onto it including Half-Life/Counterstrike, Unreal, Tribes 2, etc. In order for them to run well, I would have at least 128MB of RAM.
