Hello guys i'm trying to buy new system.
I bought a new CPU its Ryzen 5 5600x i'm looking for motherboard and ram for this system.
I'm thinking about these 2 motherboard.
ROG STRIX B450-F GAMING II OR B450 Tomahawk Max II

If you guys have any other suggestion please share with me. Just note Micro ATX is not enough for me.
Also im thinking about this ram.

Corsair VENGEANCE RGB PRO SL 16GB (2x8GB)
I need 32 GB ram so im thinking to buy 2 times of these, so i'm gonna get 4 ram right? There is also 16gb version available to buy atm but is there noticiable performanse difference between 2x8 or 2x16gb? Thank you so much!
