Every component has a useful life expectancy. If you think about the old pentiums or athlons, even the most powerful cpus of that time are relatively slow now. Gpus like the GT series or x1600, which were top of the line then, are seriously under powered now. What you are looking at is a 6 core, overclockable, Intel powerhouse of a cpu and arguably the most powerful gpu in a 980ti. Both those are going to be good for years before software makes them obsolete. With DX12 etc around the corner, somewhere, that's going to make better use of multiple cores and gpus even stronger. So as strong as your components are, the warranties will be long gone, and the components themselves so old and worn out, long before they are as obsolete as pentiums and athlons are now.
