New PC needed, Laptop doesn't cut it

[Mylexiuss]

I won't bother listing it's specs but I have been gaming on my laptop for some time now and it no longer performs as I would like, so an upgrade is needed.

I would like a decent gaming PC however I'm on a fairly tight budget around £600-£800

I haven't done much with hardware before so any help would be greatly appreciated.

Thanks

Does price include keyboard, mouse, monitor?

I already have a keyboard and mouse but will need a monitor
