So much great info, thank you all!

This was exactly the info I was hoping to get.

I think we may ending up getting the S.O. a laptop as she'll use it more for work, etc. and gaming as a bonus. I think that will work best for her rather than buying 2 separate devices as she'll need to upgrade her laptop anyway at some point.

I'll probably build a desktop. I guess I could start buying components one at a time as I find good deals. Doesn't have to be all at once I suppose.

Ideally we would just play split screen on console. But we're not waiting another 2 years + for that to happen!

Thanks all!
