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 ?
Al will depend of your electrical cost. Higher it will be, higher I recommend you to prefer the RX 470s. With the price I'm paying, that's the one I chose.
