Original Matrox Mllenium, then a Mystique with a Rainbow Runner add-on.
edit ps, Funny thing is I probably had something "before" that but didn't know what they were as they were part of systems. Not sure if my thinkpad of the time (likely the 7 series) had NeoMagic or not, but I think the old Thinkpad had a 1MB Neomagic, I know it's replacement the 380 did; but the first stand-alone discrete would be the Millenium.
