I'm building 2 rigs i bought 6 rx 470's for my first rig should i buy r9 390's for my second rig ? Less used r9 390 second hands with warranty cost like 255-265 dollar in here(these cards used 2 month without oc) and rx 470's cost me 235 dollar. Any tips ?
If your electricity cost is more than 0.15 to 0.2 dollar/kWh, it is better to buy the RX 470 or 480. Otherwise, buy the 390.
