Help building a PC

[PatchworkPhoenix]

I've been in the market for a new pc for some time anbd want to get the most for my money. I'm sure someone out there can help me get the most for my money and get the best parts with what i have. I budget is around £1700 with some wiggle room if needed. The pc will mainly be for gaming and would like to play the newest games with relatively high FPS (Especially MMORPGs.)
I've never built a pc from scratch before so if you can link a pre built PC that would be helpful but I'm sure I'll be able to build one for cheaper if you could link all the parts and some helpful ideos on the matter ^.^

Thank you for all the help ^^

Do you need everything or just the main unit (cpu/motherboard/ram etc)?

Something like this maybe, there's some room for peripherals like keyborad/mouse etc and possible extra case fans. Maybe spend a bit more on the monitor whatnot.
