Where to connect the 2nd monitor?

Question

Video cards

I use 2 monitors of the old sample (TN matrix). Since there was no HDMI, I connected one via the VGA-Display Port adapter - a GTX 1070 video card. I connected the second to the built-in, since in theory this should load the video card less. In fact, I can’t play and watch Youtube, well, or 480p . I
plan to replace the monitors with new ones, in connection with this question. How will it be more productive? Connect both monitors to the video card, or as it is now but without adapters.

Answer 1

It makes no sense to use an embed with such a discrete video. Connect all monitors to it.

Answer 2

Multiple monitors can be daisy-chained via the display port to the main graphics card
