So my current build is in my signature I built it beginning of November last year and I'm looking to get about a 4 year run out of these parts so technically coming up on year 1; however, I'm lookin to replace my i5 with an i7 6700k and the 6gb 1060 with a 1080ti. This has been the plan from the beginning though I am wondering if it is worth it or should I just upgrade to a 1070 and call it a day? After the end of four years (technically 5) the water cooling will come out and this will be given to my grandparents and little cousins as their gaming/browsing rig so I don't wanna leave em with complete shite either. Suggestions on what you all think is best i.e. keep the i5 and upgrade to 1100 series, vega, or volta when they drop or I7 and 1080ti, etc etc
