Nvidia released a free Steam demo that lets you virtually unbox and install a GeForce 8800 GTX in a 2006 bedroom.
It’s called GeForce 8800 GTX – 20 Years of a Legend, made by Dylan Browne with Nvidia support. You get path tracing, DLSS 4.5, and a CRT-era room complete with Crysis on the desk.
It needs at least an RTX 4070 (RTX 5080 recommended).
Timing is interesting given current GPU prices.
