I was keeping an eye on various sites for about 6 months or so, but not really trying as I wanted an NCASE M1 and they weren't shipping to the UK at the time due to Covid. Got the case a few weeks ago but missed the 8080FE drop where quite a few people managed to get a card from here.
The following week was the 3080Ti launch and I'd setup alerts with Telegram. I didn't want one but looked at the time to get a feel for how the process worked - followed the link to the competitor site but got no buy button. Then the 3070/3090 alerts came through. Was trying to get a 3070 and while doing this the 3080 alert popped up (which is the card I really wanted). Immediately clicked on the link and after a few refreshes the buy button appeared!
So effectively I got a 3080FE on my first real attempt. I very much put this down to right place/right time and a heavy dose of luck. I'd installed Telegram on my laptop that morning which helped as I'm much faster with a keyboard and mouse than phone. It also helped that I'm still working from home so have my personal laptop next to me.
Edit: 14 years from join date to first post!! Didn't realise I'd never posted before as always come here when building a new PC
Should also add I hadn't upgraded in years - was using a Radeon HD 7950 so was definitely in need of a new card!!
