For the hefty price tag you would hope this is a five star item. I'll be honest. I read the reviews from other sites and when I hit the order button my heart sank. I was coming from an i7 4790k and thought that the performance gain would be lackluster.

I was wrong, I was very, very wrong. Holy god. This thing is a monster. When I opened the box angels sang from above, the heaven's opened, Jesus, God, and the Holy Spirit all ran to me and screamed "I can't believe you bought this! It costs sooo much and no one needs it!" While true, if you're looking to do a ludicrous build, this should be your cornerstone. Overall, an excellent purchase, and something I would recommend doing at least once in your life if you have treat-yo-self money.

TL;DR: If you're even bothering to read this post, you should go ahead and buy it. If you're looking for someone to tell you that you don't need it, and you will be happier with an i7 and won't regret not picking this one, you're going to need to look elsewhere.

Absolutely love this beast! If you had told me last year that there would be a 10 core CPU that overclocks to 4.7Ghz like it's nothing I would have laughed at you! Here we are though and I could not be more happy with where technology is today! This is a very powerful CPU and while it is a little hot, it's nothing a delid can't solve! Well worth the money and I would recommend the 7900X looking for a good enthusiast processor!

2nd review for this CPU and I have had it for a little bit longer now and I have to say I LOVE IT! Lightning fast and overclocks LIKE A CHAMP!!! I honestly could not ask for anything better! I'm not a fanboy for Intel/AMD/Nvidia/etc.. but I am a GIANT fanboy when it comes to tech and this processor makes my inner fanboy nerdgasm daily lol

Wonderful CPU ! Temp is low with water cooling.. Could easily OC to 4.9 but stopped at 4.6 for now since I do not need the extra performance.

For the price you better hope this is worth five stars.

This thing is a monster. Everyone said, "I can't believe you bought this! It costs sooo much and no one needs it!" But I do NOT regret buying this monster at all.

The cpu is fast but way too hot at the Intel boost settings. The 2 fan liquid cooler will not get the job done. Next week I will upgrade to a 360 radiator

Selecting the I9 7900 was the correct choice for me, well for gaming the most cores needed are 8 from what I researched. I9 was 10 and performance is great. A real Beast!! It was delidded and binned by Silicon Lottery @ 4.7GHz, Currently running at 4.3 GHz smoothly. Will raise the speed when I get a little more familiar with the new board.

Definitely gets hot when running on higher clocks.
