Coming from someone with 12gb, 16 is overkill.
Sabertooth line sucks and in reality you never need more than an i5.
Hmmm.... I honestly was looking at price, I'm trying to keep it low on purposes (right now as it stands it's 808 + any shipping) I could PROBABLY get it lower if I dropped to an i5 but I dunno ... I'm mainly going to be using it for XIV and any games I have now (or will get :p) as far as the Motherboard goes... I honestly know jack squat about what's good and what's not so I just picked what it suggested I get with the CPU (I guess it's based off what other people got? I dunno)
