    Great, reliable, stable OC CPU for the price
    Purchased this new from Amazon back in September for my new build. Using a Corsair H115i AIO. I'm really impressed with the 5820k. It wasn't my first choice, had my eye on a 5930k atleast, but do to my budget and reviews online, i pulled the trigger on the 5820k. So glad I decided I went with this one. I have mine OCd to 4.3Ghz with no issues and usually hovers around 50c-60c during full load. Yea it only has 28 PCIe lanes...but Im running a Nvidia 1080FE's in SLI and it handles any game I can throw at it. This CPU is really a great all around processor for a good price.I highly recommend to anyone that cant decide on a LGA2011v3 CPU. Like I said it only has 28 lanes and it does very well with my SLI setup. If you are doing M.2 or PCIe storage setups along with SLI, I would recommend a 5930k or better with 40 lanes. However, if you only want 1 GPU and the M.2 or PCIe storage, the 5820k can handle it with no issues.5820k @4.3Ghz/Asus X99AII mobo/32GB Crucial Billastix2400 RAM/ 2x 1080FE SLI/EVGA 1050watt PSU/ Thermaltake Core V51 case/ Samsung 850 SSS 250GB for boot/Seagate 2TB HDD.

    Reviewed in France on June 14, 2016
    Très bon processeur, j'ai mis assez longtemps à me décider entre ce Intel core i7 5820k et un Intel core i7 6700k.
    Certaines vidéos sur internet et différents articles m'ont bien aidé à le choisir : tout simplement, c'est ce qu'il y a de mieux sur le marché en ce moment. Le rapport qualité prix est vraiment excellent pour un hexacore.
    Ancien utilisateur d'un i7 2600K durant 5 ans, je me retrouve donc aujourd'hui avec ce processeur de 6 Cœurs et j'en suis très content.
    Je l'ai choisi pour jouer et faire de l'encodage vidéo.
    Ma configuration actuelle :
    - Couplé avec un Noctua NH-U12S pour refroidir le tout, il est très efficace.
    - Mémoire vive Corsair Vengeance LPX (4x8GB) en DDR4 (2133Mhz) 32 Go
    - Carte mère Asus X99-A Carte mère Intel ATX socket 2011 V3 (super bien pensé, le bios est simple d'utilisation)
    - Un SLI de GTX 660 Ti (que je vais bientôt changer car les jeux deviennent très gourmands)
    - SSD MX200 500 Go.
