I have a 1 year old build using a TUF Z270 MARK 2 board, intel core i7-7700k kaby lake processor cooled with a corsair hydro searies cooler, 32 gigs of 2133mhz crucial brand ram, 2 DUAL-GTX1070-O8G graphics cards connected with an sli bridge, a samsung 960 evo m.2 ssd drive, a 2tb wd ssd drive and 3 samsung 24 inch curved monitors. One of the hdmi outputs are connected to an oculus rift. How long will this be good for gaming until I actually need to upgrade parts?
