  This keyboard is outstanding because it can withstand spills, and can be easily cleaned by just running it under the faucet. However, it was only $31 when I bought it in 2013, and I find it rather unbelievable that it costs $75 at the moment.

  Just about perfect in every way: feel of the key strokes, ergonomics, weight, key sound when typing, function, etc.

  Just installed it. Seems to run a tad warmer, but not an issue so far. It's running very smoothly. Great Product.

  Very fast CPU. Doesn't hesitate to open anything at all. Unzipped files using WinRAR and it extracts files at blazing speed. This thing at idle runs nice and cool. I have a Cooler Master Seidon 120M liquid cooler installed and it runs around 34-37 Celsius during idle. Liquid cooling only shines when you're overclocking. But in terms of speed and processing power, this thing will not lag on you. This will rip through any conversion and extraction of files. Buy It. If you're on a tight budget, then maybe an i5-4690K will suffice. But if you have the money, this thing is very future-proof and will be reliable for many years to come.Overclocking:I overclocked it using an Asus Z97-A motherboard. It was able to achieve 4.7ghz at 1.245 volts. Runs steady and fast. Temperature was running at the high 70's to low 80's. I have a poor mid-ATX case, so a good case with lots of fans will definitely be able to achieve a greater overclock. I used AIDA64 to run the stress test for a good 10-15 minutes. Temperatures ran around high 70's to low 80's all 4 cores. That was hot, and it was my limit. Temperatures in my room were in the 80's.To get to 4.8ghz, i had to increase the voltage to 1.30. That's a big jump in voltage for just 100 mhz extra. And my CPU was running too hot, so i didn't want to risk it. Anything below 1.30 volts didn't even get me to the desktop. It'll just blue screen and restart on me. Definitely needs a lot of juice power if you're overclocking to 4.8ghz. And as a personal preference, having fans blow directly on the CPU cools a lot better than a fan that blows hot air out. Fresh, cold air blowing directly at the CPU is always a plus. Downside is it'll build up dust a lot faster. A fabric softener installed in front of the fan to catch the dust will suffice.Side note:UPGRADE YOUR COOLING SYSTEM!!! Liquid cooling is preferred. Air coolers are good. But you will always get better speed with liquid coolers. Without overclocking, this CPU runs at 4.0ghz and temperatures reach around mid 60's to low 70's. And that's only at 4.0ghz. So definitely buy a cooling system.

  this was an upgrade from a i7 950. I was considering the 6core haswell e, but when you add mobo,ram,and cpu you end up spending $300 more. This a very good cpu. Overclocks to 4.4 on sabertooth z97 no problems.

  Processor is super fast, uses all its cores very efficiently - way more processor power than I need now, but Im trying to hedge the continuing trend for bloated inefficient slow packaged software for as long as I can

  Excellent performance. Requires very little power and super responsive.I upgraded an FX8350 to an FX 9590. The latter caused consistent crashing and freezes. Also, very power hungry and high temperatures.I'm very happy that I upgraded to the i7-4790k. Motherboard is the Asus Maximus Formula Vi. Worked like a charm. No BIOS updates required.

  Wow.....this cpu is so fast.... I had this cpu for about 3 months and man it was worth the money! I upgraded from AMD FX that was 3 years old and chip blows amd out of the water! I still like AMD because it cost a lot less but i was able to get this on a good price so i decided upgrade my entire rig.I haven't even overclocked this chip but its still fast as heck!
