i just ran a 3dmark test on this card recently. just built a new rig and this is the card i decided to go with because of the good reviews it has gotten. i ran 3dmark and got a very low score for the rig i built. I ran a graphics test only on it. and my results was an average of 18.53 FPS.. is that normal? i think its low. is there something wrong wit the card?
