In the 2000s and early 10s, I would tell friends that $1000 is all you need to spend for a complete tower of hardware - at least, a sweet spot of performance and value. $250 was /pricey/ for a GPU in 2005.
But to be fair, like cars from the 80s to now, they do a lot more these days. I never installed a Physx processor for Crysis but now that's on the GPU.
