Seagull, thanks for your input, it answered this question for me too! I purchased a Voodoo card this past weekend, downloaded the drivers you referred to - and it's great!
Now for my question - Since I installed it my computer handles video much better, but every once in a while (maybe 4-5 times a day) the monitor appears turns of for a second then back on. I hear a click when it happens. I don't loose any of my work - the computer continues to function, but the monitor goes black for that second. Do you, or anyone out there have this problem with the Voodoo 3-2000 card on the Mac?
