Will Sapphire AMD/ATI Radeon R9 270X with Boost OC 4 GB DDR5 Graphics Card will support crossfire ?
will it support 4 way crossfire technology ?
Indeed, but as unknownofprob said the scaling just isn't worth it. Even at 3 cards you start to get 250-260% instead of what you could expect to be 300%
Crossfire (2 cards) is getting pretty good though, scaling is getting close to complete with around 185-190% performance compared to 1 card.
