Unless you have bad luck with Computer hardware, Computers typically last 5-10 years, if not more, with proper maintenance and care(like not spilling stuff on keyboard or not running it when its hot to where the fan or cooling system has to work overtime to keep the components cool). I have a PC from December 2010 that's still going strong, although its GPU went bad back in like 2014/2015 so we had to replace that component. Outside of that, its still running :D and yes... I desperately need a new rig because I have hardware from like 2008(and its 2019... a decade in Technology is an eternity). Just trying to wait as long as I can for Intel to get their act together. Been wanting a 10nm CPU for ages now. NVidia hasn't disappointed with the RTX 2080, although I might grab a 2060 to save a bit of $$$. Plus if I keep waiting, DDR5 RAM might be out lol.
