I don’t think scalpers will go hard on the 5090. 40 series was not that hard to get at launch, unlike 30 series. 5090 is really pricey and it’s a much riskier proposition to scalp. My guess is initial launch sells out very fast, and then it won’t be too hard.
I think 5080 will be scalped hard and any FE will be very hard to get. My plan is to try a best buy order immediately once available, and get one immediately at Newegg and cancel the Newegg if BB goes through. As I remember last time, BB launches right at the correct time. Newegg just randomly has them show up hours before midnight on launch day.
