Ok, so I am a noob when it comes to the technicalities and performances of ram, my rig consists of; gigabyte fx990-uda3 mobo, 8gb DDR3 1600, sli-bridge EVGA 560gtx 2gb. My question is, what are the pros and cons of 1600 vs. 1866 vs. 2000 DDR3 ram and if sticking with my Kingston DDR3 1600 ram is sufficient for gaming or is it worth "upgrading" to the higher end ram. Plz guide me.
