If you want to buy a 4090, this review is for you. Now before I get started, I just want to give a shout-out to my sponsors dognose and shirif. They know about games that 0wn.
Once you start looking into buying the 4090, you have several different websites you can choose from - NewEgg, Amazon, Best Buy, and NVidia. Just kidding, NVidia's website just linked to all the others.
I first tried the Best Buy (BBY) website since that was the official drop point for NVidia and had the super cool looking founder's edition card. I was dead set on the FE card, but that was a mistake. As soon as Best Buy added inventory to the site (5 mins before the official drop time), botters and scalpers snatched them up by using a special link. I kept refreshing the site like an idiot after the official drop thinking BBY was late putting them up. Nope, BBY was sold out. While I was refreshing, all the other cards dropped on the other sites and sold out fairly quickly.
I was half looking at NewEgg's site and almost bought the watercooled version of the card which was like 300 buhks more (should have done that), but no, I was dead set on the FE card thinking it would drop later (plus, it looks super cool).
In any case, everything sold out by the time I found out that the FE card was sold out already. Then I was browsing Reddit and found out you have to append something to the end of the link so that you get automatically put in the queue. I tried that for a bit with an auto-refresh script, got added to the queue as Best Buy added more cards in besides the FE edition, but by the time the site verified me, the card was sold out.
I got real close once and got all the way to checkout with one card. Unfortunately, Best Buy thought I was picking up the card instead of having it shipped and wouldn't let me check out since it didn't think the card was available locally. I had to watch the timer with my reserved card count down from 10 minutes, and there wasn't A FEEKIN THING I could do about it.
Then I used my auto-refresh script on NewEgg thinking maybe they would restock eventually, and they banned my IP. Amazon didn't really have anything, it was all gone by the time I looked. All. Gone.
Long review short, buying a 4090 really, really sucks. If you really want to buy one, set aside your whole day and prepare for getting nothing!
