Great Processor
Built a new computer using my old Alienware Chassis and existing ATX OEM 1000 watt power supply. Purchased Gigabyte X99 Gaming 5P motherboard, Intel i7-5820K processor, Seaagte 1TB internal SATA hybrid hard drive, LG 16x Blue Ray disk drive, 4x Crucial 16GB DDR4-2133 memory cards, CPU Fan LGA 2011, XFX AMD Radeon R9 390 8GB graphics card, Windows 8.1 64 bit operating system, and Logitech MK710 Wireless keyboard and mouse($2020.15). Everything works perfectly.

A really awesome 6 core processor
If you're looking for the latest and greatest LGA 2011-3 that offers the best bang for your buck, this is your processor. Sure, the 5830k has a few more PCI lanes.. but who's going 4 way SLI? If you're doing more than 2 way SLI, this isn't for you. There just aren't enough lanes. The 5960x is an absolute beast, but it's also 3x the price...
This processor is blazing fast, make no mistakes. Plus, it overclocks REALLY nicely. I'm using a Corsair H100i GTX and can get this to a stable 4.2ghz at a nice and cool 40c

Great step into the x99 family
Great processor, got it on sale as an entry into the X99 chipset. Having the much needed ram capacity with 8 slots is a huge step up from previous CPU and chipset. Easy to overclock and extremely fast multi-threading processing.
