So now you're moving the goal posts to top dollar? No we're talking around £100 more.
On your house and car analogy why didn't you just buy the cheapest house that's liveable then or buy the cheapest car that gets you from A to B? It's pretty damn obvious everything isn't about the price, of course it's a factor but it's a long shot to call it the only one.
I wonder how many 7900x's have sold compared to the ryzen 1600? Just showing that price doesn't matter.
