It gave me a boost of 2100 in 3dmark2000. With the voodoo3 I got a score of 2900, and with the geforce mx, I got 5000. Though I've seen people score higher with a geforce2 mx with the same cpu speed, I think those scores were fake. I've been playing midtown madness 2 and the graphics and speed have improved 3 times what they were with the voodoo3. Other than that, I don't really have any 3- D intensive games.
Graphics are clear and fast.
Make sure you put the DV up to at least low or medium. It makes the graphics look so much better. And since the card runs at low heat, you might as well overclock the sucker. Though I did stick a fan on the gpu since I'm overclocking it. But it added no extra sound.
