Pros: -Bang for buck
-Bought mine for $200 at microcenter!
-Able to keep up with a GTX 1080 at 4K
-Power efficiency
-Usually within 1-3FPS of 6700k for $100 less
-Mine overclocked to 4.6Ghz @ 1.275v with a hyper 212 evo (a $30 cooler!)
-Even overclocked at 4.6Ghz my max tamps are below 70-80c
-Huge upgrade over FX8320
-Many platform upgrades that I was missing on AMD like PCIe 3.0, USB type c, M.2, DDR4, etc.
-No more stuttering in GTA V
-My system just feels faster and more responsive than before
-CPU and my motherboard support USB type c for my Nexus 6P
-6600k, Gigabyte Z170 SLI XP motherboard, and 16GB of 3000MHz DDR4 RAM cost me only about $400 with tax

Cons: -AMD Zen may prove to be a better value in the future
-No stock cooler may be an issue for some
-Need Z170 chipset for best overclocking
-Huge jump for a user of the current AMD FX lineup but it would probably be considered a very minor jump if you have something like a 3570k or newer

Other Thoughts: If you're just gaming like me and don't do any rendering this CPU is a no brainer when compared to the 6700k. It has almost all the performance (especially when overclocked) of an i7 in games for much less money. Also if you're lucky enough to live by a microcenter you can get these for around $200.

My system specs:
Rosewill Tyrfing case
6600k @ 4.6GHz
CM Hyper 212 Evo
Gigabyte GA‑Z170XP‑SLI
EVGA 16gb (2x8gb) DDR4 3000mhz
Zotac GTX 1080 Amp edition
Sandisk Ultra II 960gb SSD
Seagate Barracuda 2Tb
Thermaltake smart power 700w PSU
AOC 28" 4K monitor

Pros: -It may not be the fastest SSD but coming from a HDD you will be blown away
-Game load times are significantly faster
-Windows 10 boots in less than 10 seconds
-Faster file transfers
-Cheap for 960GB
-SSD prices have dropped so much, I remember back when I bought a 120GB ssd years ago for a little less than this 960GB

Cons: -Not the fastest but what do you expect at this price point
-No cloning software included, not a big deal for me but some might care
-I reinstalled Windows just to avoid any possible issues

Other Thoughts: When I first bought this I was weary from all the bad reviews but for the price I paid at the time ($250 in September 2015) I was willing to risk it and I'm glad I did. Maybe I just got lucky but I have had the drive for 11 months and I have had no issues with it. SSD's have come down in price so much that it just makes so much sense to buy them now.
