i managed to get 32 570's from alternate.ch ..they lasted about 5mins on their site. i had been searching all of europe for a week with no luck untill then,they arrived today 
Do you think it's worth to buy 1 RX 580? They are at 300eur
The 580 8gig is a good card.About 25mhs stock,I do not mod mine,it may void the warranty,not sure though.Better safe than sorry
The 400 & 500 series use around 125 watts whereas the 300 series can be as high as 350 watts,but the 390 8gig gets 30mhs stock,at least my MSI 380 is
So less power is better & the resale later of 500 series will be better too
