I've got a EVGA 670 GTX FTW and I want to ask what you think I should do.Do the up-step program to a EVGA GTX 680 Classified or should I wait untill after march and get another EVGA 670 GTX FTW and do a sli set up. The thing is, it better to have one great card then two good cards. So $180 and I get a great card that last 4 years and I can get a second one much later and do sli. So what do you think I should do.
