I have an Athlon XP 2000 motherboard (2.0) w/383 ddram and a very old nivida card. I recently bought a Gforce 3 with 64mb. I took the card and tower to a reputable pc repair shop in town and he called me back a day later to tell me the card was no good and that I should take it back. So I made the trip back to BestBuys and told them the story. I went in the back with 2 techs and they plugged it in 3 different test rigs and they all played great with great graphics. Hell I'm not against pulling my old car and putting the new one in right here. I have found updated drivers from Nivida.Does anybody have a suggestion or hints that I should be aware of before doing this........my OS is 98SE Thanks for the help.Dwayne
