EDIT: Actually, the first true GPU i owned came with a slapped together PC my mom bought at some "shop," and it was a ATI Mach 64 (or 128? Circa 1995/96). I loved that PoS! How I became a PC enthusiast, young me took it apart and rebuilt it, even upgraded the DX2 33 to a DX2 50 and eventually all the way up to a DX4 100!
When I could finally work, a Voodoo 2, came with my uber (expensive! stupid young me!) Gateway Destination XTV!!! Pizza shop job FTW!!!
First card I bought trying to pump life into that same aging system was a Radeon 7000 PCI edition! It was absolutely terrible, and that's when I started to learn more about what GPUs were.
Next card was in a freshly built rig, the king and legend itself - Radeon 9700 Pro!!!
