Casual look on a used PC I bought (R7 5800X + RTX 3070 TI) 

It's running at 3600 MT/s, which we commonly say as "3600 MHz". it's DDR = Double Data Rate so you multiply 1600 MHz to 2. It's normal to be this way. 3200 Mhz is actually 1600 Mhz --> 3200 MT/s

around 800 USD

I'll be doing some videos about it first ahaha!
