Not sure how smart it was, but I went to OriginPC and got a rig that included a 5090 (they didn't specify which specific model, so it could be Founders or some random overclock or who-knows-what).

I priced out the individual parts I selected and its about $1200 more than MSRP all told, but I opted for their best warranty, so if I assume that $500 of it was "I don't feel like building this from scratch, or sourcing the parts I'll never find, and possibly getting a dud, and having a half-built rig sitting in the corner for 3 years", and another $500 for "maybe I'll win the lottery and get a 5090 who's MSRP is $2500 instead of the $2000 for founder's", (and another $200 for tax and shipping), then I don't feel like a /total/ moron (feel free to correct me in the comments).

~$6200

Also, I don't feel too bad about getting a 5090 over a 40xx because (I can't find anywhere for remotely close to MSRP, and) my current card is a 3080 in a laptop I've had for 4 years, and I'm hoping this new machine lasts 6-8.
