Been using nvidia cards/drivers for the past 20 years. Never had an issue with the drivers breaking or depreciating(?) my hardware. My current card, a 1060 6gb, has been in constant use for the past 7.5 years with no measurable drop in performance, using official drivers.

It’s likely that most episodes aired before the dawn of home video recording (early 80s) are completely lost media. NBC and other networks weren’t in the habit of archiving tape-to-air media.
