Backstory: After the Antec Earthwatts 650 bit the dust and the GTX 780 also fell into death's hands 2 weeks later, I started to plan out a x79 build for myself since my i5 4460 and GTX 780 rig was starting too much for me to play it properly (ie stuttering in overwatch, bo3 and PCSX2 emulator)
First, I did purchased a x79 huanan gaming board from aliexpress (this boi right down there if want to buy one)
After researching the quality is good enough to handle a mild overclock from xeons and supporting quad channel but unfortunately, I bought it when Chinese new year, never got shipped and the order ended up being canceled (refund came after a week).
So I started to search on ebay and decided I'll try to win these auctions. Got really lucky with that intel dx79to board on ebay for only 110 (instead of 200-250 dollars for it). It does have some missing features (no heatsinks on vrm, no usb 3.0 connectors and a basic bios) but it'll serve me well thanks to having some overclocking features and having quad channel (just like most x79 boards).
Got average deals on the Xeon E5-2670 (a better FX-9590 in every way), Noctua HD-D14 (has 2 SilenX iXtrema fans on it that gives Nocutua fans a really good run for it's money), and a Fractal Design Arc case that's still pretty decent. I've gotten all these deals from ebay, letgo, cragslist or ebay.
Gotten an absolute steal on the RX 580 8gb for only 40 dollars since a mining from Pueblo no longer needed it. Thermal paste and pads are all in good condition and the fans are still in decent condition.
After everything came together in together, the end result of the price was only 350 dollars (reused my hard drive, keyboard, mouse, dell monitor and headphones) and the performance was staggering.
I've been able to BLCK the cpu to 3.46 ghz (3.14 ghz on all cores), managed to undervolt the RX 580 by -37 mV less volts while still being able to overclock the Core to 1465 mhz and memory to 2125 mhz (8500 mhz effective).
Overwatch no longer stutters thanks to the increased ram count to 16gbs and it scaling on 6 or higher cpu cores and while Team Fortress 2 runs slightly worse due to the lower single core speeds, it also no longer stutters when youtube is playing in the background of the alt tab menu of steam.
I plan to replace the Xeon E5-2670 to a Xeon E5-1650 (aka a i7 3930k, a 6 core 12 thread chip) since it has an unlocked multiplier and is able to reach to 4.5 ghz on these boards thus far more suited for gaming and the 2670 is able to only overclock by BLCK.
Overall, I've extremely happy of the end result of this pc.
