[BATTLESTATION BUILD!] Second hand GPUs; things to watch out for~~~
When buying a second hand GPU, be sure to test it using benchmark software and observe the GPU internal attributes using MSI Afterburner
Certain things to watch out for during heavy load~~~
Temperature of GPU
Stable or fluctuating core clock
Release date of the GPU
