Corsair XMS3 6GB (3x2GB) DDR3 PC3-12800C7 (1600MHz) Tri-Channel (TR3X6G1600C7) [TR3X6G1600C7]
£182.99 inc VAT

the price makes no difference as they are so similar so just looking for best proformer, ive seen in some spec sheets that the dominator has a bus speed of 1600mhz where as the xms3 is only 800mhz, also the xms3 has a lower CAS
any help appreciated
