-Integrated graphics. (Prince of persia, Doom, etc)
-Random card in the computer.
When i started being interested in video game graphics etc:
Geforce Mx2 (God I loved that card)
9800pro (Great card, served its purpose)
X800XL (Completely transitional card, sold it a month after I bought it)
7800GTX (Died on my 2-3 months after purchase
X1900XTX (Still going strong, good card but makes lots of noise, its big and its hot)
Next on my list is probably an nVidia card. Don't think ATi is up to par yet since the 9800 series.
