Sapphire HD 7770 Vapor-X OC Edition Review @ OCC
 

In the end, I'm impressed with the card for what it is. It's a perfect card for a mid-range/mid-budget gaming build. The price point really sells it; the graphics are there to play what you want; just not at the highest "Ultra" settings. The factory overclocks don't leave a ton of room to play the overclocking game, but you are guaranteed 1100/1300 delivered to your door. Whatever you get after that is just an added bonus and you won't hear it when you crank the clocks either thanks to the Vapor-X cooler. It also being a member of the 7000 series and with not much competition in the same price range from NVIDIA makes this card a winner for any builder or gamer on a tight budget. This card sells itself.
