I vaguely remember reading something about the latest high end Nvidia gpu's (2080 / 20180ti) being more expensive this time around due to a lack of competition from AMD, and the GPU generation prior (1080, 1080ti) also being expensive because people were using them to mine Bitcoin or something. I doubt the upcoming Nvidia gpu's will go back to being as cheap as the gtx 90's, but with more competition, perhaps we'll see some better prices than what we have now, or at the very least, some faster price cuts.
Be that as it may, the gpu is just one part of a pc, without it we are still looking at like $600-800. then add whatever gpu might come that matches it.
It takes genuine talent to see greatness in yourself despite your absence of genuine talent.
