They care more about graphics then game-play.
Good luck as every GPU old and new is marked up three times it's MSRP. So yeah not reasonable anymore unless you get a cheap bidding price on E-Bay or Alibaba.Typically I update the GPU after 3-4 years, and I'm never buying the latest ones, so the price is reasonable. It won't cope with all options at "FULL" on flight sims like DCS, but for most other games it's fine.
