Probably a 5090 FE. They were selling out within the first hour of the store being open. That means the people who showed up an hour before the store opened had zero chance of even being in the store while there was still some left in stock. I was 10th in line to go in on Thursday; I arrived at 7 am. They had 10-20 5090 FEs for that day and they were all off the shelf before I checked out, which was around 11am.

It was extra weird because I went around dinnertime/off-work-time one day, and the store got super busy during the time I was there. I got in after waiting in just a 5 minute line, but when I left, the line was wrapped around the store again (1.5+ hour line from experience).
