I ran them in crossfire and they aren't quite a year old yet, No OC of any kind. They were bought at newegg an best buy respectively.
They run BF 4 between high and medium settings at 50 to 60 fps on my system. I'm interested in around $100.00 for both of them.
Would not get to mail them till after 1st week of deer season, maybe after thanksgiving would seem better. You will need 2 6 pin power connectors
from power supply to plug them in and 2 pci-e 16 slots on mainboard for this setup. They run very quite and don't draw much juice. They ran BF 3 all turned up
and was main reason I bought them. Still have original boxes for them.
PM me if interested and I will try to get back to you as soon as possible.
