Hi everyone, are there big differences between the 1070 TIs? The only one I can get that is least overpriced in my country is the Gainward (this one http://www.gainward.com/main/vgapro.php?id=1008&lang=en). The only other one is MSI Aero for around 600 usd (which is sold out everywhere here), all the others are like 650-700 usd lol. Should I go for the Gainward? Are there significant differences in hashrate between different brands? Thanks in advance
