It DEPENDS on your CPU and USE. LGA 1155 then Vengeance or Ripjaws X - best to use 1.50v RAM. Otherwise, other than a DDR3-1333, the Dominator's are 1.60v~1.65v and are IMO better for say LGA 1366.
Problem - The Vengeance are not as good, in comparison to other Sets nor the Dominator, for OC'ing (higher than Rated).
Problem - Gaming on the LGA 1155/SB, there is no benefit >DDR3-1600 with the SB. However, the LGA 1156/1366 'do' see an advantage to >DDR3-1600 IF the CAS Timings are ALSO LOW or 2~8FPS increase. Further, to use >DDR3-1600 you will need an AMD 4 core (~DDR3-1800+ limit), AMD 6 core (~DDR3-2000+ limit), SB (~DDR3-2400+ limit) and i7 9XX (~DDR3-2200+ limit).
