If the 3000 is only $30 more than 2133 I would think its faster in most scenarios even if the latency is rather bad. I would probably pay that difference.I ordered mine on August 5th. Still have time to return if but unsure if its really worth it to pay more for say ddr4 3000(extra 30 bucks)
Especially since I don't really overclock.
I know why get a k and not overclock? Like the higher stock speeds and too afraid of making a mistake and frying my pc.
