PAR-FAIT
It's a great speed of calculation, the quality-price ratio is very interesting! I've been using it for a while now and it's a great value for money. It's a great replacement for my old DDR3 motherboard and my I7 4770 pross, there's a real gap between the two, it's very pleasant to use.
I recommend it, as well as the LDLC assembly which is also perfect and an excellent customer relationship ;)
