The Radeon RX 6900 XT Toxic LE in the company of other graphics cards will not be overlooked. The 360-millimeter liquid GPU cooling is a rare thing that will definitely attract attention. Still, it’s a rather controversial piece of hardware. There are several reasons to opt for this madness (in a good way). But it is also necessary to know about certain flaws that it has. We need to be demanding and strict in this price category.
