well truthfully i just dont trust the pci card yet, had a HIS9200se card and it kept playin games, only way i could use the pc was with the tnt2. Once the 5200 is workin fine ill get rid of the tnt2.
The 5200 supports dual monitors as it is ;-)
Managed to solve the problem tho, i installed both cards, and booted into safe mode. removed the drivers for the 5200.
Booted back into windows with only the 5200 installed, which made the driver utillity find only the new card and installed drivers, restarted etc.
Once it was up and running, put the tnt2 back in and booted into windows, and hey presto!
Both cards are workin at the moment.
Must say that the 5200 is running alot smoother then the 9200se i had previously!
NFS2underground looks realllly good, and i can finally play halflife counterstrike with d3d!
Cheers for the help on the fourm, completl forgot about safe mode!
