The Asus cooler is awesome I had it on an old 1080. I suspect the vega 64 is too much for it though.So asus shown us that you cant make gold from **** ... If they cant get it going better only Jesus or God himself could..
Cant see anyone not stupid buying v64 over 1080 aib.. Maybe with freesync monitor... MAYBE
In terms of performance an AIB Vega air card simply won't compete with the LC version however good the air cooling so we already know that top AIB cards won't better the LC or a stock 1080fe.
