This makes it even easier to wait for AMD to drop their lineup. I'm very interested to see how much 980ti's will drop to on the used market (roughly $415-$450 right now). While I'm not sure if the 1080 would be enough (for me) for 4k gaming, two 1070s or something from AMD's new lineup I'm sure will surpass by far my previous 390x crossfire. I'm very excited.
