I am looking to upgrade from my Sapphire 7950 OC. Originally was going to get a 1070 when they get released. But is it worth waiting until the AIB boards are available (and not constantly sold out), or just buy a gtx 980? I might do/try occasional 4k gaming, but probably stick with 1080 or 1440p. I'm not an fps snob, and 30fps is fine with me. As long as it's playable. Any thoughts? Also I'm not looking to spend over $500 which rules out a 1080 or 980 ti
