The G.Skill and Corsair ram are pretty much equal in performance and quality. Corsair did just release a premium set that I have been looking at and trying to figure out if it's much better then the Vengence.
By the time your ready or the new system your talking about DDR4 will be out.
CORSAIR Dominator Platinum 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 Desktop Memory Model CMD8GX3M2A1866C9
They don't have a 1333mhz set and the 1600mhz is the lowest for this new set.
