For gaming, 4 max, 3 if you want it to actually work well. Most of the time its better to just go with the single more powerful card over multiple crappier ones.

depends on ur motherboard, it can support upto 4 but after 2 cards scaling is very bad.

I remember seeing some guy post a build log type thing where he had 4 690's in his system and the replies were all people just laughing at him.

i think 4 phsyical gpu with 1 gpu chip each or 2 x 2chip , 8 is pointless or meaningless unless there is a driver for it or mobo that support it

anything higher than 4 is for supercomputing. There are no consumer grade products that scale past 4 in any way.

Windows limits only 4 GPU's from what I herd, but I think its more of a driver limitation. Only reason I can think they limit to 4 is because most motherboards and cases are to small for that many GPU's. There really in no point in adding more then 4 anyway. I have a friend with 4x HD6970's and it scales bad in a lot of games other then Battlefield 3 & 4. But 3 of his cards run really well in most games.

I run 3 GPU's, 2x HD5850's and a HD6450. Only reason I do is becuase the HD5850's both have a dual monitor flicker problems, Only way to fix that is to force my cards to run in 3d mode, it saves more power to run 3 cards but let powerplay kick in.
