i am building a gaming pc
first i thought of getting a saphhire 7950 vapor x edition with boost then i saw that it is costing very much.
So i thougt of combining two 7770 if it can beat the 7950.
 
Solution
HD 7770 CrossFire performs about the same as a HD 7850 or HD 6970 or a GTX 650 Ti Boost if I recall correctly. So a HD 7950 definitely beats that.
First, I'd not recommend doubling up on any sub $150 card...... this is especially true for Crossfire

As for the 7950, it just gets topped barely by the 660 Ti in fps but the frame latency issue separates the two considerably. And, as above, the 660 Ti leave a 2nd card possibility whereas CF still an iffy proposition at this point. If ya going to stick w/ a single card, I wouldn't argue hard against the 7950 tho.

Its a mixed result, in some games, CFX 7770 is almost as powerful as a single 7950, while in a few others such as skyrim, its even slower than a single 7770, read : http://www.techpowerup.com/reviews/HIS/HD_7750_7770_CrossFire/1.html

if the 7950 is too costly, you could go for a 7870XT/7870LE as they are made from the same chip as the 7950 but with some shaders disabled , which is at the same price range with a 7770CFX setuparound $250-ish, moreover, it will produce less heat and no micro stuttering which is a problem faced by AMD CFX setups
