I recently installed a geforce 6800 256-bit 128mb graphics card and im havin problems playin games, i've tried several different games and they all seem to be missing images and textures. My pc is a Media center PC athlon 64 3400+ with 2 sticks 512 mb PC3200. This card is brand new so i dont know whats the problem. I installed the drivers that came with it but and when i try to update it says that it has the most up to date driver. Can any one help me fix this?
