I've had so many! My first true gaming card was a 4MB Guillemot Maxi Gamer 3D back in the day (3dfx Voodoo 1). I had some oddball cards including the old ATI Rage Fury Maxx and even Intels first dedicated gaming card which was the Intel i740.
The Nvidia GT 7600 (Galaxy model) was a bargain GPU at the time for the performance it delivered. I had a HIS Radeon 7950 IceQ was great at the time as it ran extremely quiet and cool with decent performance.
I've had quite a few decent cards and a few odball, underrated or outright terrible cards too!
