"Bad opinions few years ago"
Well you could've gotten some good opinions of Volkswagen a few years ago, not that it matters now.. So it shouldn't matter for AMD cards now, right? I'm trying to say you can have some opinions on everything, most people believe what they're marketed to.
As I'm already commenting on this:

• Overclocking yes or no? If no go for the i5-6500 and H170 Chipsets. Cheaper, same performance. If yes, stick to K and Z170.

• Power Supply is overpowered. Your configuration will need 300 Watts under the utmost maximum. Under gaming rather 200 - 250W). Also the PSU is of rather midranged quality. You could go for higher quality, same price, as for instance with the Seasonic G-Series 520W or Coolermaster V Series 500W.

Rest is absolutely fine and no, you don't need an i7 for gaming (why do I always see some people saying that?). But as long you can read benchmarks properly, you've probably figured that out yourself.

PhysX isn't always "better stuff" and enabling those effect can cuf of FPS on TitanX by 20. Most of the time GPU tests are made with whole PhysX / GameWorks turned off to not mess with results. You can see comparison between GW turned on and off here - ultra settings with and without HairWorks in Witcher 3 (separate tabs)

PhysX has only two jobs in games in actuality: to reduce framerate and to introduce more clipping bugs than normal.

Well, I am a bit late and probably somebody wrote it already, but video/picture editing makes use of Nvidia's CUDA, so PhysX isn't the only thing that argues for Nvidia. ;)

Thanks for your event that leads here.

Oh, great then! :D BTW I totally recommend u the hyperX RAM. ;) you can't go wrong with that.

You should be happy to have such a beastly PC at work.
Im jealous.

Praise Socrates for this magnific masterpiece

in 3 years time I'll make my build, call me back by then and if I get into space, I'll give you a ride :)

As a piece of quick advice, don't buy 16 gb now, no games use that much RAM, the only reason you would ever need that in 2015 is if you are doing heavy video editing, if not then stick with 8 GB. Buying another 8 GB stick in the future will be much cheaper.

Prusy, what do ypu think about mycase now? :»

I have 3 3Tb and counting...

You could head towards the amd route. Their cards are showing promising results on dx12.

Yeah, I would recommend the r9 390. It's more powerful, little bit cheaper, and that 8gb of vram would serve you plenty in the future. The 390 uses much more power than the gtx 970 but your 650 watt power supply should work well with it

z tego co ja patrzylem pare razy to tam mozna spokojnie popytac i odpowiadaja wiec troche dziwnie napisales ze 0 pomocy

Minecraft was programmed using Java. You should get 300+ FPS so no issues there, but you'll likely still experience random hiccups. They'll only become more frequent with more mods, especially 100 of them.

Mind you, I haven't played Minecraft for quite some time so things could be drastically different now. Last I heard, they made some change which kept a lot of the popular mods using an older version of Minecraft which wouldn't help things either.

PhysX is a gimmick. Sure, its effects might look neat in videos, but they tend to be implemented in ways that make them more distracting than helpful in immersing the player into the game. Plus, PhysX effects tend to reduce FPS by quite a bit. It's really not worth it.

That said: I can't link you to a test where PhysX effects enabled doesn't kill framerates on AMD GPUs. Generally speaking, PhysX effects can't be enabled at all for AMD GPUs. Not to say that PhysX doesn't work at all without an Nvidia GPU, just some of the more computationally expensive (think fluids, smoke, cloth, hair, particles, etc.) parts are disabled/aren't as detailed. Most (all?) of the important physics stuff is done on the CPU, anyway.

I'm not sure what the current situation is, but nVidia was sabotaging AMD cards attempting to do PhysX for a while.

Id rather have Steam Controllers :) And later HTC Vive / Oculus Controllers. :)

I also had to wait few times for delivery because shop site wasn't up to date and even if it stated that they have something in warehouse they had in fact wait for shipment. This suck.

So if you already have CPU and cooler be gentle with them D: Noone likes forced unions xD

And if you have everything except GPU and HDD you could assemble it to see if it is working. Adding GPU after having everything in case is super easy (you just put it in PCI slot and connect power cables) and to add HDD to SSD you will just have to leave one SATA and power cable free. And you will have to plug in monitor to motherboard. You will be even able to play less demanding games in that way :D
