ATI HD 4770 X4: Only 3 out of 11 Games Effictively Use Crossfire X
 
What happens if you put four HD 4770 in CrossfireX and run 11 game benchmark on this config? A multitude of benchmarks results! Especially interesting is the fact that only 3 out of 11 games properly support CrossfireX above 2 GPUs; all other games show almost no scaling. Going from 1x HD 4770 to 2x HD 4770 results in ~58% performance increase overall; going from 2 to 3 video cards the net result is ~20%. Adding a fourth HD 4770 adds another ~13% in some cases. Not very impressive all that. A HD4770X2 might still make sense, but for anything else than 3DMark benchmarking, 2 GPUs is the limit.
