help using two different video cards in the same machine.

[David Mora]

I just want to know the benefits of running two video cards in the same machine, I have four monitors and three of them don't have HDMI connections and I am using a GTX 750 2G with four ports, 2 DVI and 2 HDMI, so I use a second video card GT 730 for a small screen because the DVI connection, and also because if I am not wrong, when I am playing in a surround mode with the other three monitors, I can watch HD movies in the small screen with not problem. sorry for my long history, but I just want to know if do I get any benefit of doing this, because when a run the hardware monitor, if I play something in my small monitor with the GT 730, shows that is using the processor of the GTX 750, and the speed of the 730 GPU always stays at the lowest speed.
Is better to buy an adapter and remove the second video card?

Thank you...

If your system works, keep it. I don't believe that the gtx 750 can drive more than three screens at a time (it can't according to the official specs).

The GTX 750 model from Gigabite, does four monitors at the same time.

I just want to know if is worth it to keep it inside because of the use of energy and heat. Do I get any performance boost?

You might get a performance boost in games that use PhysX. Otherwise it doesn't make much difference.
