After some tests on different CPU intensive applications (weather modeling, encoding, last game, calculation software ...), I'm really not disappointed, performance is really at the rendezvous.
Only flat, fan delivered by Intel (hence one star less). During testing, I went up to 100 ° C. So I replaced with a noctua and where happiness: 30 ° C IDLE and a max at 56 ° C with the same previous tests.
I have not yet tested the CB.
I think being a quiet moment with this processor.
About AMAZON, it was my first order and I'm not disappointed, ordered on Thursday at 13h, received the next day. Impeccable parcel!
I recommend this processor and AMAZON.
