See... This is what people should be doing. Going from a 580 to a 980. Good move man. I see people just giving up on their 770's and 780's to get the 9xx series. For Christ sake... I bet you could get a 4gb GTX770 from some dumb bastard eager to sell on EBay for around 200 bucks. Nvidia is just having money thrown at them right now. I think moving from a 580 to a single 980 is a good choice. Then you can sli them later.
