I am running ati radeon xpress 200 series it runs and works but every once in awhile i get massive horizontal mixups and crash..... amd athlon 64 bit chips are still buggy so i deal with it .... i wish there was a way to update it but im not sure how to. ive gone to ati.com and AMD.com and its a touch confusing for me heh if anyone has advice other than ( GET A NEW CARD) it would be helpful
