2 monitor setup

[Olly2101]

I'm thinking if I should get a 2nd monitor or not, the thing I want to know is will haveing a 2nd monitor have an effect on my fps in games. The 2nd monitor would only be used for light browsing, Spotify etc. Any help please!

If you don't use it for gaming, the effect on FPS will be minimal, few FPS at worst.

it will have next to no effect
