I am planning to upgrade my graphics card for my desktop. My current system has a single AMD Radeon HD 5750 and it has served me very well in the past as I was able to max out the settings in every game. However with the advancement of PC games which require more power/processing, I thought it was a good idea to upgrade my graphics card.
After days of local vendors to see what is available and hours of web browsing and reading reviews, I narrowed my search to 4 cards:
Radeon HD 6990
Radeon HD 7770 (http://goo.gl/A1wAI)
Radeon HD 7950 (http://goo.gl/jlVfg)
Radeon HD 7970 (http://goo.gl/3NDvM)
Any help choosing among these cards (or suggesting alternatives) will be appreciated. Also will I replace the one I have or is it possible to add a second graphics card and combine (cluster) their power
P.S I'm a huge AMD fan and accept nothing else so please no recommendations for Nvidia
For those curious, after reading the recommendations here and some googling I decided to go for the HD 7970.

if you own a few oil companies , then you can consider the GTX 680, it is a insanely expensive card but still offers the best performance (especially when overclocked)
It is also not very loud (you will most likely never hit the temperature needed to push the fan to 100%
also currently has better driver support.
the 7970 is also a great card (though I have never personally used it) but from the benchmarks, you wont really notice the difference between the 7970 and the 680 with current games.

7970 every time, but as much as you seem to hate them, the new Kepler chips wipe the floor with Southern Islands cards from AMD. Consider a GTX 680, you won't regret it over an AMD card, I promise.
