ASUS Rog Maximus XI Hero Intel Z390 B Stock

[yakacm]

I'm looking to upgrade my Asus Z390 Prime A motherboard to ASUS Rog Maximus XI Hero Intel Z390, just to see if it helps with OC instability and I notice there are B grade stock up on OC:UK, just wondering if anyone from OC:UK could tell us why there is so many of them B Grade, 7 in total? Is there a reliability issue with them? Also, don't know if I am being naive here, but you only get 90 days guarantee from Overclockers for B stock, but do you still get the full manufacturers warranty with them? Another quick question, I am pretty sure the new A stock Maximus XI Hero was £239.99 last night when I was looking and now it's £299.99 was I dreaming that or am I just unlucky that I didn't pull the trigger last night? Wonder if I could use Waybackmachine to order it, lol?
