The a50s need the usb and optical cable plugged in to work well or it will constantly cut out. I bought some for xmas and learned the hard way. The install instructions are bad when you need them for pc
Thanks for the advice, was looking at two asus 290's but may look to see if anyone has those gigabyte versions in the for sale section in the next week.
Without starting a new thread, what does everyone think one all the used r9 290s? Knowing most were used to mine. Worth the $200 price tag or no? I don't know enough on how bad they would perform after being mined 24/7
