1 out of 5 eggsMine was a dud.

Pros: Nice looking card and I like the way that the heat from the card is blown out the back of the system. Was delivered quickly and in great physical shape.

Cons: Was very unstable to start. I tried the drivers that came with the card, but after win8 failed during driver install twice, a friend who recommended the card came over with his system to play some co-op games. Using the latest drivers, and the new beta drivers, we could not get the drivers to install and reboot correctly. We took his card out of his machine and placed this new one into his machine and the system BSOD while booting. I tried his card in my machine and first try the drivers installed and rebooted correctly. Traded cards and with the new card now back in my machine, I was able to post and start win8 but there were artifacts everywhere and then the system failed and win8 tried to recover. It could not recover until I removed the card. I have my old nvidia card back in the computer so that can at least use the system.

Other Thoughts: Since these are now out of stock and I wanted to eventually get two like cards to crossfire together, I think I might want to try a more recent 7970 instead of another 7950.

Pros: Runs really cool while mining LTC, and I like that it's based off the reference 7970.

Cons: Didn't come with a crossfire bridge.
