First of all I'd like you guys a few questions:
- have any experience in gaming at all. Did you play on consoles before or will this be the first experience in gaming?
- What kind of games are you expecting to play?
- What is your total budget? I understand that you don't want to break the bank, but a budget number would be pretty helpfull
I'm asking because firstly, I wouldn't advice going all in on a full gaming PC if you don't know yet if it actually will be used. It would be a shame to spent for example $2000 dollars on a PC that after 3 months only will be used for office work.
The kind of games you're expecting to play I'm asking because if it's not going to be graphic intense games, you can spend again $2000 on a PC but it won't be fully used and you can go cheaper. Games like Prison architect
or LEGO games won't be as demanding for your PC compared to games like Red Dead Redemption 2
or The Witcher 3.
The budget would be really helpful, also to know what else you need to include into that budget (monitor, mouse, keyboard, speakers / headset etc).
With those pheriphals I again wouldn't recommend going all in on it. Especially because if it turns out gaming is really you guys' thing you can always upgrade or replace them. Spending $500 on a monitor would be overkill, like @Oussebon
said, arround $150-200 you get a perfectly fine monitor. Do you want to go better you can still do it and use the first one as a 2nd monitor. Same with mouse and keyboard. It would make no sense to me to spent like $250 on that when you don't know if in 3 months time all it's doing is office work.
