WINTERLORD :
i thought gpu makersd stock the new gpu's so they have many avaible for purchase the day it launches? i mean i know gpu miners buy them up but thought theyd atleast last longer then a couple minutes when they came out at 9am
Not really, each re-seller is going to get a fixed amount. Even without mining there can be shortages. When the GTX 1080 came out there was a shortage of GDDR5X which kept stocks low.
Other times there have been yield issues on the GPUs themselves. I think the Fury cards had issues due to the very large dies and scarcity of 1st gen HBM.
And keep in mind the people that buy these things are just like you, and there are literally dozens of us.
