gondo :
I have issues with this build I'm not fond of the reliability of Acer monitors. Same goes for Sapphire Video cards and MSI motherboards.
I like the first build with the 6600k CPU. At least it's the newer socket 1151 and an Asus board board which I prefer.
I'm not a fan of Samsung either due to reliability issues. I like Crucial SSD. They may not be as fast but an SSD is so fast anyways it's like comparing Lambo to Ferrari.
As for power supplies both choices were good but I'm an Antec fan again due to reliability. NZXT cases are nice but there are some quality issues. The few Corsair cases I've worked with have been beautiful. Design isn't everything...quality is a big thing in cases. I don't care how good the look and layout of drive cages are if the quick release tabs are a pain to use and they all break. I want top quality construction when it comes to cases.
I never used an NZXT case and I'll admin the design of them is superb. But I've read some stories about their quality not being up to par with Corsair, Silverstone, Lian Li, Antec, etc....
As for the video card. Get what you can afford. 2GB of onboard video is good enough for 1080p. If you plan on gaming at 1440P or 4K then it's worth paying extra for the 4GB+ models. AMD has eyefinity while NVidia has lower power consumption and access to the shield streaming gaming service if that interests you. I also seem to notice more games performing better or supporting NVidia. That being said I currently use AMD because they are usually a bit better value.
As for video card brands. I prefer Asus and Gigabyte. I've also read great things about HIS and own a couple of them myself with no issues. I've use cheaper brands like Sapphire and Powercolor in the past with reliability issues. I used MSI products years ago and grew to hate them. Not reliable at all. Things may have changed in the past 8 years.
So I guess you didn't like anything mostly because of brand? well.. you're a very picky person, this might not work for you, but it might work for op, I can assure you Sapphire cards and MSI are known to be the best AMD card brands currently with the best cooling, it has three fan coolers to keep the card cool, MSI are good too, but sapphire is better, gigabyte are HORRIBLE, as for the motherboard, this is an all time favorite motherboard for medium budget builds with AMD cards because it supports crossfire, personally I prefer Asus over MSI if I had the choice, but MSI comes second, as for the power supply, I was about to choose evga but then decided to go a bit more premuim and went seasonic and 850w as a future-proof in case OP wants to add another 390x..
For you might think Nvidea always rule, but I say no, Nvidea are ruling on the edge, they are best at low end low budget GPUs (like the gtx 750 ti and gtx 950) and the High End (like the gtx 980 ti and titan x) but since the release of the 300 series from AMD and DX12 (not really a factor but wanted to add that because it's true
) it has been ruling in the mid-(low)high GPUs, for example we all know that the r9 380 beats the gtx 960, and the r9 390 has the same or give or take better performance as the gtx 970, except it has 8gb of vram, for $300-330, and the 390x has the same performance or give and take a bit less performance than the gtx 980, with 8gb BUT it's only $399-409 as oppose to $500 with 4 gb, after that gtx 980 ti wins over the fury x..
About the monitor, Acer is up there with Asus (of course Asus might be better) IDK how to explain it to you, but I guess that's your preference.
About the ssd, really? how did you run into reliability issues worse than crucial with Samsung ssds? were you running raid 0? Sumsung 850 Evos are known to be reliable SSDs, I haven't run into any issues so far..
THe s340 is one of the most famous NZXT cases out there with the NZXT H440, they are only bad when comes to cheap cases like the source 220, but this is very good quality..
Something I might agree on is that OP doesn't need an r9 390x, he could've been fine with an r9 390, but I think he would appreciate the extra performance over a more premium case or brand
The CPU, again you don't NEED the latest Skylake CPU, if he wants to spend the extra money on a "newer" cpu he can go ahead, same goes with everything else, you seem to want the "best of the best" but remember there is a budget and we don't want to sacrifice some performance for it, I could've went with a corsair case + Asus MoBo + Crucial SSD + Antec PSU, but do you really need it? no.
I think things have really changed over those 7 years...
You get my point, have a nice day
P.S. excuse my English if it's all over the place..
