Good choice - the 2nd gen TRs are getting a price cut.

Keep in mind that the 2nd Gen TR uses quad channel memory, so you may need to start with 4 sticks of memory. Right now you can get 32Gb memory kits on Newegg for around 99USD.

My box will be getting Corsair, but that is because I am going with ECC memory. I have been using it since 2006 (My 1,1 & 4,1 Mac Pro) and I am simply more comfortable with it. Biggest issue right now is that the 32Gb sticks are simply unavailable at the moment. I'll be needing to go with them (@ 167.99 a pop) due to the dual channel memory slot for an X570 board. I have 96Gb on my current system & I like the breathing room (and the ability to have multiple poorly coded Adobe & DAZ apps open at the same time).
