At the time the case was released, there was no assumption that EVGA would leave the GPU market, and potentially the entire market. EVGA has ended nearly every program and the z790 has been the only release in months, with no further details except for more programs coming to an end. So, yeah, there was an assumption that an upgrade path was available, before the announcement of programs being closed. Step up was an option when the e1 was released. Bucks were an option when the E1 was released. Affiliate and rewards programs were an option when the e1 was released. A lot has changed since EVGA left the GPU market.
I’m hoping evga is still holding something close to the chest, but recently evga started giving users information on how to repair their products that they would never release in the past. Hopefully if evga decides to end more programs, they will open source their software so that users can create their own support, but only time will tell.
