I recently had to replace my Boot drive as it died recently, while doing this i decided to install my old GTX 660. It is an OEM card I got for 60 (Aussie) bucks a few years ago. It held up remarkably back then (about 2019) as I could run most of the games I was interested in on low-medium settings. I know that since then the 600 series lost driver support and so forth, and I know it definitely isn't going to perform as well today as it did back then. I also know that the RTX 2060 super is starting to get old but would absolutely demolish any 600 series card every day of the week.
My thinking was that my 2060 super can be my primary GPU and the GTX 660 can supplement it by doing secondary tasks. In short, my thinking was to have the GTX 660 serve as a load spreader. My goal was to extend things until I can afford a new GPU. As replacing either card is not an option for me currently.
I have always rathered keep old stuff useful, I hate the idea of just throwing old tech in landfill as soon as it gets even slightly too old.
I know this sounds more like a justification, but I guess my real question is that instead of turning old tech into e-waste; What should we, as gamers, do with our old graphics cards?
