Over here, Vapor-X sells for 1,499 Euro, and 7900 XTX for 1,269 Euro (including 19% VAT in both cases). And sure is quite a price difference for such a FPS difference. And then there is the RX 7900 XT, going for less than 1,000 Euro now.
For the time being, I am fine with the RX 6700 XT (OC) though. At 1440p and ultra settings, I do get at least around 70 FPS in a number of games I tried so far.
A better GPU would increase the FPS, but it won't improve the built-in graphical assets of many a game, which are ever so often designed to run on consoles, where even the PS5 comes "only" with a peak performance of 10.3 TFlops. And a PC port usually doesn't redesign all of it, which means that a RX 6700 XT with 12.4 TFlops is not easily falling behind in that regard, especially when alongside a resonable CPU and a Gen4 SSD (which the PS5 and Xbox already have, for the increased transfer rate as well for the lower latency).
