Pros: Nothing more to say. I bought two of them to use with a 5930k. They overclock fairly well (I got somewhere around +250MHz core, +350 memory). I get an average of 130 fps playing GTA V on max settings, 1080p. That is the only game that has really even questioned their power. It rips through FIFA 15, destroys Minecraft (with shader mods and 256x resource packs), gets a very consistent 300 fps in CSGO... There is really nothing that stops them.

Cons: expensive, I guess.

Overall Review: buy two of them. Worth it.

Pros: Let me preface this by saying that I am not an MMO gamer. I don't play WoW or Diablo or anything, I play Counter-Strike. If you play a game where you need to bind lots of different things to all the buttons, this is probably as good as it gets. The buttons are all instantly recognizable and in fairly convenient places, unlike mice where it is essentially a numpad on the left side of the mouse

Cons: The mouse, no matter what thumb rest, pinky rest or palm rest you use, will always be uncomfortable. It is not a mouse to use for over 2 hours because your hand will ache. It is, at times, unbearably heavy. Using it for a first-person shooter would be a terrible mistake.

Overall Review: This has been a backup mouse for the majority of the time I've had it. During the short times when I would play Torchlight II, it was very useful.

Pros: I've had this keyboard for about 6 months and have had 0 issues, the sign of a good keyboard. Mechanical keys feel great, as always. The keycap remover and the rubber topped keys are nice as well, although I found myself going back to the normal keys eventually.

Cons: none

Pros: Works like new, no problems; feels like the old Deathadder 2013 in my hands which is why I bought it.

Cons: razer synapse is really bad

Pros: I'm coming from a 3570k @ 4.3GHz. That processor bottlenecked most demanding games (e.g. GTA V). With this one, it seldom passes 40% utilization. It overclocks quite well, too. I haven't done a ton of tweaking with it (why would I, the only thing that can utilize its power is a stress test) but I easily got it to 4.7GHz @ 1.4v. Doesn't run as hot as people might have you believe.

Cons: Uses a relatively proprietary socket type. There is only one upgrade, and it's $1100.

Pros: Pretty much the cheapest DDR4 RAM, seems to work well (although I don't do much that utilizes all 16GB anyways)

Cons: For some reason, my computer kept hanging and crashing when I used it at 2400MHz. I downclocked to 2133 and haven't had any issues since. Don't buy this for overclocking.
