I'm working on a project—a very dumb project, mind you—and I was trying to acquire the two current-gen flagship GPUs: an Nvidia RTX 4090, and an AMD Radeon RX 7900 XTX.
In some weird stroke of luck (it has been difficult to find either in stock), I was able to get one of each this week.
(lol at the size difference...)
Besides exorbitant price gouging, Nvidia's ownership of the crown in terms of GPU performance remains in this generation, as the 4090 blows past any competing card so far. But AMD's 7900 XTX was poised to be the best value in terms of price, performance, and efficiency (at least compared to any Nvidia offering).
