What to install first on a gaming pc

[Rusty Shackleford329]

Just ordered my first gaming pc and I'm not sure what to do now, so what do I do first, what should I install

Does it boot up fine?

If so, here are some good options:
Get an antivirus while your PC is still clean
MSI afterburner
Do you have any LEDs or case fans? Get whatever program that brand recommends.
Geforce experience (or whatever your PC supports)
A browser
Games
