It would look like this:
Making a game for a graphics card sounds rather silly tbh. Developing for at least 3-4 GPu's sounds more reasonable and covers more users out there. Don't forget, the majority of games on PC always feature low, medium, high and Ultra preset settings to choose from, to scale to what hardware you have. Games like Star Citizen look really beautiful, but they can also be dialled back visually for those with hardware that isn't near the top end (not talking potato weak).
Also I wouldn't pay £100 for a game that's just about visuals. I want visuals, proper physics and believable animations , a world that comes to life and one that can be explored and interacted with. If a game managed to achieve all that and provided a great deal of replayability, then I could consider going for said game, but I'd still wait for a price cut.
Mankind, in its arrogance and self-delusion, must believe they are the mirrors to God in both their image and their power. If something shatters that mirror, then it must be totally destroyed.
