Experience: 3 Months


Run really cool
Low power consumption
Great overclocker
XFX so great warranty
Ugly heat sink
Blow hot air inside of the case
I overclock it to 870/1020 from 750/800 stock. I can hear the card at all when idle and when gaming, the sound of game cover the sound of the card. It perform like a 4850 without the heat and noise.

Experience: 2 Days


Price!!! Performance, crossfire scalability.
Ugly, Small (Con?) Driver support.
This card is amazing. I bought it for $125 and don't regret it at all. The drivers for Windows 7 got released today and it's working flawlessly.

The price is amazing for its performance. Easily the best card in it's price range.

Crossfire these puppies for some super fps :)
