No worries, I have some clients that do video for a living, and both they, and those that do it for fun, hobby, part time, etc all prefer faster DRAM. The base DRAM spec on your CPU is 1600, but they easily handle faster sticks. My two primary rigs are 4770Ks and I've got 32GB with each, one running 2666 and the other running 2800 DRAM and both are rock solid. 2133 or 2400 is a good choice for both the higher data rates and price, 2666 and up is pricier
