I've been running a voodoo 3 2000 for over a year, and it has got me by on any and all games. Good card, and the 3000 is better.
I just purchased an asus geforce 2 mx and haven't played any games on it yet(going to install q3 in about 15 mins), but I can tell you that the v3 is a good card, but it is ageing, really you should just go with a geforce 2 mx card.
A good mx card is the hercules one, its ram is faster than the reference geforce 2 mx, and its faster than all its competitors.(183 as opposed to 166 i believe). I really should have went with the hercules, but I thought this one had dual monitor and tv out, apparently I read wrong as it showed up with just one monitor port on the back
If you want tv out and dual monitor, you can pick up the asus mx card for around $140, but READ CAREFULLY, Just because it says full retail doesn't mean that there aren't two versions at retail... Found this out the hard way.
The Hercules board without tv out or dual monitor is probably around $150.
