I'm not saying that the approach doesn't have some logic: the card works and works well. But unfortunately it has its limitations and mainly, and depending on the model, they are the dissipation and the quality of the components.
Let's look at it from the following point of view: Can you overclock it enough to put it to compete with something more current than a gtx 660? Without breaking it within ten minutes, no.
The best way to take advantage of somewhat outdated GPUs is to lower the graphic quality, try something more extreme that might work for a forum point, but at the cost of the card itself in a not very long term.
Now that I remember, I still have an S3 trio that works… ;D
