Help needed for building pc with budget of 1000 pound

[oni one]

hi, iv recently decided to build my first ever computer for 1000 pound(ish) to better suit my needs which are..

1. i need to be able to make music using music production software with plugins without any problems when working on large projects

2. i need to be able to play games at the best quality i possibly can within a budget of around 1000 pound(give or take maybe a hundred or 2)

3. i need to be able to upgrade parts and overclock when im ready to start experimenting with trying to get the best out of my pc.(any recommendations as to what bits i should upgrade would also be helpful and recommendations for watercooling would also help)

again only got around a grand to spend at the moment, massive thanks in advance to whoever can point me in the right direction

Here is where i would start and then for your gpu wait a week for the amd 300 series as these could cause prices to drop or offer an alternative card but with what's currently out i would get either a 970 or 290x with this build
