What is the maximum stable overclock for GTX 750?
Estimated maximum stable frequency for your GTX 750 is around 250MHz. Many users who have done overclocking report gains between 40 and 60 MHz, especially in games like Rainbow Six.
It's hard to predict anything. Each setting varies. You need to keep raising it until you see artifacts (odd lines and colors), then adjust back by 15-30MHz for stability. Unigine Heaven or Valley are good choices for testing overclocking on the move. I recall my setup was 220MHz+ Core and 550MHz+ memory. A GTX 750 wouldn't fit well there; upgrading to something like a GTX 960 would be better, as it's more stable. You might find a GTX 960 for around $50 used or $970 used, which is worth it. Just ensure you have at least a two-week testing period. Also...

Unigine Heaven or Valley are good choices for testing overclocking on the move. I recall my setup was 220MHz+ Core and 550MHz+ memory. A GTX 750 wouldn't fit well there; it would slow down the CPU too much. Upgrading to a GTX 960 is better—around 50$ used or 970$ used, both on eBay. Make sure you get one with at least a two-week testing window. Overclocking might only give a 15% improvement at most.

If you choose to upgrade, opt for the 4GB version GPU since some models come with a smaller 2GB one. This should provide better longevity.
