As the title says - I'm looking to buy a second monitor soon, and I need help choosing whether I should buy a 1980x1080 one, or a 1366x768 one, considering I currently have a 1366x768.
However, if a new CPU, or graphics card, or whatever would be more beneficial, please tell me and I will buy that before.
My current build is this.
I will have £200 to spend.
Note: I will be buying this in July when I get the money, and I use my rig for gaming.

Thank you, fellow PC builders.
