Ultra for the next 3 years is dicey, your best chance is top of the line now: 980/290X/780Ti, but high is doable I'd say with 290/780/970. 280 is pretty much a a rebadged 7950 which is a 3 year old card, so you've already gotten your 3 years out of it basically if you buy it now. Similarly the 280X is like a 7970. I built with 3 years in mind with an i7 4770K and CF 290Xs as well as an i7 5930K and SLI 780TIs. I'm not upgrading until December 2017 unless something dies or I win the lottery. I also got EVGA 1300W G2s PSUs that come with 10 year warranties.
