I wont comment on how much ln2 you spent cause then there are other factors like price, availability and others.
Then I can also mention that it isnt fair cause I wouldn't have 15hr a day to bench, etc etc.
Everyone has his own perspective obviously which makes sense to each one of us.
I dont know how you consider your kit but as far as I know Galax tested the kits for 2000 12-12-12 1.9v. Mine runs once every 10 spi (example) runs with 1.97v (your mems might scale with voltage; mine dont) on impact which is bad (4060 is no go).
As for the guys who bought xxx amount of hw its their issue.
For me it always comes down to how much $$$ I spent and if it worth it.
