That is low...and you're only running it at the High preset. On the ExtremeHD preset, you should be seeing scores of 2650-2750 or so with Dual Radeon 290s and an i7 4770k.
Do you have your cards overclocked? If so, are the power sliders maxed at 20%? What temperature are they running because they may be thermally throttling to protect themselves which is resulting in your low score.
Or the High preset may not be stressing your hardware enough, try it again on the ExtremeHD preset after checking the things above.
