Geforce 4 Ti4400 and it was fantastic. I remember back in the day you could buy a Nvidia GPU and it could still be decent after a few generations. Whereas today one generation behind Keplar can be total garbage compared to Maxwell in new games until it finally gets patched months later...
a 4400 ti 2-3 years after launch was a lot more horrible than Kepler was, things moved really fast back in the day...
I never had a 4 ti, I had a 3 ti 200 at some point, and had the 4 MXs (which were old tech, geforce 2 for the most part, but since most games were DX7 in 2002 it was kind of OK, they had fast memory and core clocks), but those were interesting days for sure,
TI 4600 was very nice, and the ti 4200 with some OC a really nice option,
but, it's difficult not to remember how much better the Radeon 9700 looked.
until the Geforce 6 appeared and it always impressed me a lot more than the X800 series, because of SM3.0 support mostly, but also the pipelines unlock on riva tuner was a lot of fun for people buying 6800 non GT/Ultra!
