Buying DDR3 RAM

Looking to buy some more RAM.
My Mobo can handle anywhere from weak 1333 to high 2133 Mhz & can hold up to 32GB
(Asus Crosshair V/Thunderbolt)

I'm looking for around 8GB+ Right now I have 4GB high performance (DDR3 1333)
But I want something higher than 1333 & will probably trash or sell the current new RAM I bought for the high RAMs. unless you wanna buy it go ahead offer.
AMD VisionTek High Performance DDR3 1333. 4GB. (2x2) it's Brand New

Just put what RAM you have Brand & price,Mhz as well. Thank You
