Building a new i9-9900K system soon. Rite now, I have available at a local computer store: 1. Gskill Trident Z RGB 3600 C18 2. Gskill Trident Z RGB 3200 C16 Both same price. I can get either of them at anytime from my local store. Or is it better off for me to order online and wait for delivery of 3. Gskill Trident Z RGB 3600 C14, Priced about 1.7x higher. I don't mind spending the extra, but will there be any noticeable gains? I will be mostly gaming @ 1440p and 4K.
