Every time I started a game, the entire screen would flicker really badly and sometimes turning black.
1. Thought it was Windows 8 fault, since I only tried it on two games and no one seems to have a problem with this card on Windows 7, so I reinstall Windows. Still flicker.
2. Tried different CCC version ranging from 12.8 to even the latest 13.2 beta. Still flicker.
Came across a post somewhere about cables turning bad, so before changing out cables, I, just for the sake of it, tried plugging it into the other miniDP port.(7870 came with 2 miniDP)
Andd it works!! No more flickering nor turning black.
My question is should I exchange my card because it has a faulty port? or is the underlying problem somewhere else (cable, driver, system)??

Nope, didn't work on Windows 7 even on the other port. Everything points to the port being bad, but I only run this off one monitor anyway. Is it even worth exchanging? I don't have a backup card and would be stuck without one for many weeks.
