This is a high end build that has served me spectacularly with gaming and room for enthusiasts. It goes with a blue/black/red theme for the most part. (Edit) Since I have posted this originally over 2 years ago, I have made some big improvements on this build.
At this budget I went for the Intel Core i7-6700K processor which delivers great performance, oc, and future proofing. This card handles well when over clocked. When games get demanding in the future, This processor will have no problem handling it. To cool the CPU I went for Cooler Master Hyper 212 EVO because of it's budget cooling capabilities due to the fact that the i7-6700k processor does not come with a stock cooler. If you plan on doing some hard-core over clocking you may want to look into a radiator liquid CPU cooler.
The sexy MSI Z170A GAMING M5 ATX LGA1151 Motherboard worked well with this whole build with it's versatility and many other options for upgradability. It has SLI and Crossfire support for GPU upgrades. This board supports DDR4-2133 / 2400 / 2800 / 3000 / 3200 Ram for awesome multi-tasking. You can find this mother board at a great price if you catch it at the right time. For the RAM, I went with the red G.Skill Ripjaws V Series 32GB (4 x 8GB) DDR4-3200 Memory to accomplish great multi-tasking capability. On the original posting I only had 2-8GB sticks of Ripjaws ram.
Getting to the GPU, my choice was the MSI Radeon R9 390X 8GB Video Card for it's great 8GB V-Ram and it's over all performance. I acquired this card along with the skylake processor in a bundle deal on Newegg.com. This card along with the I7 skylake processor have great overclocking capability. You can even purchase another MSI Radeon R9 390X 8GB Video Card and crossfire for some serious gaming capability. It even runs 4K gaming pretty good. This whole build is also great for VR gaming. (Edit) Since I wrote this initially I have made a huge upgrade to the EVGA 1080TI FTW3. I was lucky enough to get this monster gpu on the first pre-order batch before the price was ever inflated.
For storage I picked the PNY CS1311 240GB 2.5" Solid State Drive for my operating system and other important applications and files. Solid State Drives are great for system start up and fast application access. For my bulk storage I purchased the Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive. It's a reliable Hard Disk Drive. It has great speed and longevity at a great price per GB. I have purchased a Toshiba P300 3TB 3.5" 7200RPM since this original post over 2 years ago because I have quite a large game collection.
To meet the demanding power need plus more I picked up the EVGA 850W 80+ Bronze Certified Semi-Modular ATX Power Supply Unit for it's great price and great wattage. You may want to go for a fully modular PSU if you have the room in the budget but this suits more than my needs.
For my dvd/cd needs I bought the Asus DRW-24B1ST/BLK/B/AS DVD/CD Writer for my basic needs because of the fact that I buy most of my games on steam and some on origin. It also is a reliable disk drive. You can always shoot for blue ray if you watch disk movies on your PC.
I initially bought Windows 7. Of-course I gave in and upgraded to Windows 10 for free. The version of Windows will be determined by what your needs are.
I put all of this awesomeness in the Thermaltake Chaser MK-I ATX Full Tower Case. This is a sexy full ATX case with great cooling capabilities. It has a great open air design and room for many huge fans. The fans that it comes with are great with LED-lit fans that have red, green, and blue colors and different patterns for extra sexiness. This case also has 2 USB 3.0 ports on top and 4 external 5.25" drive bays, 6 x 3.5"/2.5" internal 3.5" removable drive bays. There is plenty of room to hide all the cord cables in the right side panel and the left side panel has a viewing window to show off your awesome hardware. This monster even has a top-mounted HDD hot swap docking station. This case is loaded with features. I even love the headset mount. Check it out! I think it's impressive. I now have more 200mm fans for extra cooling and ascetic purposes. 2 years after this original posting I have upgrade my monitor from a Ben Q 1080p monitor to a Acer XB270HU bprz 27.0" 2560x1440 144Hz monitor. I have also upgraded my keyboard from a motospeed rgb keyboard worth $40-$50 to a Corsair K95 RGB PLATINUM.
This PC build is and was great for me and I haven't been disappointed yet. There are many options for upgrades and aesthetics. You will need a good size area as this is a full ATX case. I hope this gives you some direction. Sorry for any typos and/or bad grammar. This is my first PC guide I have written. After the original posting contained here in, The additions explained above weren't even totally necessary but I haven't regretted it! Everything has been running nice and cool with very little problems for 2 years or more. Have a good day.
