Now that the reviews are up, you can make an educated decision on whether to buy a GeForce RTX 2080 Ti or GeForce RTX 2080 graphics card, at least based on current performance metrics and features. We still don't know how they'll fare with real-time ray tracing and DLSS-enabled games at large, so there's a leap of faith involved. However, if you're ready to make the jump, we've rounded up several listings where you can buy one right now.

We'll start with the GeForce RTX 2080, because that is the only one that is available as a standalone card right now (save for a single EVGA SKU). You can order the Founders Edition direct from Nvidia for $799. Alternately, there are several custom-cooled models available from Nvidia's hardware partners.
