Yea, that requires a bigger investment though. Someone is sellin 2 7970s for $75...
yeah ok, but remember this
the 7970 when you sell it again it will be worth $50, if you can ever dream to sell it again(no one will buy it)
a 480 can still be worth $200 in 6 months or more, that is the big difference
you only need to roi on the difference between the purchase price and the resale price, not the whole initial investment
Amph please, you can sell them $100 each, instant roi. There is always a buyer for an old gpu.
