This began as a budget build, and it can be done very inexpensively with less than $375 if built with 8gb of RAM, stock cooler (yes, it can support 4.6 ghz on that one), no wifi card, no discreet graphics, Windows 7 license, and just one HDD.
Very stable system and gaming up to 4k with decent frame rates.
I would have, and probably will change the video card for a R9 290. Although tweaking the settings on the Sapphire and overclocking it from 985 mhz to 1.1 ghz has helped. Spending time on the settings did more than the overclock. Make sure AMD's Catalyst doesn't get in the way of the application/game's own enhancements. AMD does have preset profiles for many games which helps.
I love the motherboard's support for overclocking and the software bundled with it. It gives your control over almost every aspect including cpu multiplier, BLCK speed, cache multiplier & BLCK, DRAM overclocking, CPU & CASE FAN controls, and as a bonus, unlimited RAMDISK software bundled for free.
Do yourself a favor and get the Windows license from Bonanza. They sell for less than $40 for Windows 7 PRO or 8 PRO.
Didn't particularly like the case, but it was inexpensive. Same goes for the power supply. I actually didn't use the one listed on this build. I used a Kentek, bought through Amazon, 680W Dual Fan Gold Color ATX Power Supply. Do some research and get one of the modern ones if you want the case to have better air flow and a cleaner presentation. I spent some time routing wires and with zip-ties to make it half decent.
Overclocked to 4.6, which is about average for this CPU with 1.29v. Extremely impressed. It beats almost every other CPU out there regardless of price when it comes to single core speeds and value. It can hit 4.5 ghz - 4.6 ghz on the stock cooler too! Amazing processor, do yourself a favor and use separate graphics card. If you will do anything other than surf the net. If you game, watch youtube videos, or enjoy decent graphics, you will need it.
