I didn't encourage or discourage gaming. Also, mining means stressing the GPU 24-7, gaming is occasional. ... if you're gaming 24-7, then please stop doing that to, it's not good for your physical and emotional well-being :-(
In reality most mining happen with under-clocked GPU cores (and admittedly overclocked VRAM), and at very stable temperatures. The GPU that is used 24/7 for mining will be far less stressed than a GPU that is powered on and off, and cycles through a lot of thermal changes throughout the day
