Keen to upgrade something??

Hey guys im keen to upgrade Ram. Currently have 2gb x 3 Elixir 1600Mhz ram, I think its just cheap nasty ram so i was wondering if i put some quality ram in if it would make a difference?? Have a gigabyte x58a - ud3r. I think i want 2000Mhz ram but what??

Moved to the memory forum - you'll get a better response here.
