I also have the following that I'm thinking about selling to help finance additional rig upgrades since I've ROI'd on these cards:
x6 XFX r9 390s 8gig RAM ($280 each)
x7 Sapphire r9 290 Tri-X ($250 each)
x1 ASUS r9 290x ($290)
x5 MSI r9 380s 4gig RAM ($175 each) (2 cards have broken fan blades that I will be sending off to have replaced by MSI)
The guy bought 6 7950s and risers/hd/cpu/ram/psu for only $1000, don't think he will pay $170 each for a 7970 when you can buy a new 380 for that price.
I don't see in my post where I said the prices are set in stone. It's just a starting price and since I've ROI'd on them already I'm more than willing to negotiate a price so I don't have to sell them on eBay. However, thank you for your comment as it was very helpful to this thread. Have a good day!
