first of all, whats your budget?
CPU: Intel Skylake i5 6500 4-Core 3.2GHz
good choice, but seeing that you have a z170 board you could also get an i5 6600k and overclock in the future. if you want to stream and render a lot, get the i7 6700k
Motherboard: Intel Z170 Chipset ATX Gaming Edition
which brand?
RAM: 16GB DDR4 Quad Channel Red Series
dont take quad channel! z170 only supports dual channel, therefore get 2 ram sticks. this means you can upgrade in future. which frequency is this ram??
Power Supply: 850w ATX 80 Plus Silver
good with 2 cards, way too much with one card. again, which brand?
Primary Storage Device: 2TB SSHD Hybrid Hard Drive
pls not. get a 500GB ssd and a 2tbhdd. while sshd are slightly faster than normal hdds, you want a ssd
Graphics Card: Nvidia GTX 970 4GB
Second Graphics Card: Nvidia GTX 970 4GB
not good. either get an r9 390 if you want a single card, or a gtx 980ti if you want high power! multigpu setups are loud, hot, scale badly and have microlag. you know about the vram problem with the 970?
CPU Cooler: Cooler Master Hyper 212X
take 10 bucks and get something bigger and you will be able to use that one for builds in the future aswell
Operating System: Windows 10 64bit Home Edition USB
Additional Fan: [2x] Additional Case Fan Non-LED
Thoughts guys?
this looks like the typical pre-built pc crap. no brands for psu and motherboard (cause they will use the cheapest crap there). dont do it. build it yourself. its a cool experience, easy and absoluetly worth it. you will get a better pc for less.
