I paid approx $700 for a i5 with a Geforce 3050 and a 144hz screen. The RAM was weak but it was upgrade able so I got it up to 40GB, about $800 all up. It's an MSI.
The only downside is that it's such a pain to take apart and it's put together in a way where there's a very real chance of doing permanent damage when taking off the cover, since the case actually wraps around the ports and makes the motherboard bend when you apply any pressure to it. It came with 8GB of RAM out of the box, so basically unusable without the upgrade; still, I'm very happy with it atm.
They may not be dreaming. Rent elsewhere can easily be $450 per week.
