brent what's behind the decision to continue support for 400/500s and eliminate support for 600/700
With all this uncertainty about Nvidia, it seems likely that a lot of folks who bought Nvidia cards in the past will be looking to upgrade their present cards for something that will continue to be supported for a reasonable time. One might be forgiven for suggesting that they seriously consider a graphics card other than Nvidia for their next purchase.
Wouldn't Intel perhaps be a better choice the next time? The Intel video in my 2014 Dell laptop is still fully supported, and happily working in a machine that's running on Linux. Also in my wife's Dell laptop of approximately that same vintage, also running on Solus Plasma. Seems like a much better record of not only supporting their graphics cards, but also supporting Linux.
