Diamond Monster Fusion AGP 16MB (with the Voodoo Banshee chipset) on my first custom built PC.
Together with my Pentium II 412MHz, 128MB PC100 SDRAM, 17 inch Sony Trinitron monitor, and Altec Lansing ADA-305 Digital Powercube speakers, The Legend of Zelda: Ocarina of Time ran near perfect using the UltraHLE emulator. That was back in February of 1999, IIRC.
Fast-forward four and a half years later to July of 2003... my second videocard would be an ATI All-In-Wonder 9800 PRO 128MB in combo with my 21 inch flat display Sony Trinitron monitor. Spot a trend? ^^;
