So, i've already made a thread requesting help but.. I've re-looked at my budget and realised that 200 + 100 does not equal 400... But here are my requirements. I have a budget of £600 GBP for a keyboard and mouse, monitor and of course a build. The build will be used for gaming and running new games like GTA V and Battlefield One at 40-60 fps as well as possible. Ideally 40-60 fps on ultra settings.
I'd like the monitor to be 27 ". For the keyboard and mouse, I like keyboards with wrist wrests, and i'm left handed So no right handed mice.

So to sum it up...

Gaming Build - Running BF 1 and GTA V at 40 - 60 fps on ultra settings.

Monitor - 27 " or more monitor... nuff said.

Keyboard and mouse - The keyboards needs a wrist wrest, backlighting isn't necessary. For the mouse: I'm left handed and I don't mind if it's wired/wireless (same for the keyboard).

I don't need an operating system, however I do need utensils such as sound and wifi.

That's it really. thanks in advance
