Will there be a big drop in performance with a second monitor?

Question

Monitors

I want to buy a second FullHD 21.5'' monitor, since the laptop 13'' ones are too small. I 'm interested in a possible drop in performance, since the hardware is rather weak: Intel Core i3 4030U, 4GB of RAM, Intel HD Graphics 4400.
I even agree with the “Second screen only” mode, but simultaneous work raises more questions.

Answer 1

everything will be fine if you do not turn 3D on each monitor. Intel 4400 is quite a sane vidyashka.

Answer 2

Hello, everything will be fine, if only in the social. you will not sit on the network, then your performance will drop.
