I would probably start testing it with wolfram alpha queries first, just because there's loads of stuff you can look up on it. It's a great way to test the speech recognition.

A 120mm rad is the same size as one of those PCs.. I don't think you will be able to fit a lot without making that thing at least 3x as large.

This is one of those builds where you should probably just get a FX-8320, the extra cores will really help and you can spend the extra money on more RAM or a better SSD.
I have no idea about REALLY cheap graphics cards so if someone could suggest something better that'd be great.

Best you're going to get for this budget. Buy a second 4GB RAM stick and maybe an aftermarket cooler if you can.

You can get a G3258/970 PC for $750 and for $900 you could get a 4690k/970 which both are FAR better than this PC.

I must tell you that the WD Black series is really loud though. I have a WD Black and I would gladly trade it for a new silent (inferior) HDD if I had the possibility.It's just so loud.

A single 980 gets 42.2 FPS on average playing in 4K so I think either a single 980/SLI 970s would be your best bet.

However much this will put you back. You can always add another 980 if you feel like you're not getting enough performance.

I think the 750W PSU will fit.

So yeah.. This game looks pretty cool I've got to say.

Do you really have to ask...
 
just kidding

And that's just of reported bends.. If someone was anything like me he'd just RMA it.

or you could spend more and get a Lian Li PC-Q19.

5820K/mobo/2x4GB is only $200 more than 4790k/mobo/2x4GB, so if one were to spend $4000 on a PC he might as well get X99.

are you the guy that designs gaming rigs for large resellers?

I got a bit carried away and forgot about the monitor at first so it's a bit over budget. You might want to SLI 970's instead and get dual monitors. Or even get a cheaper CPU cooler if you're not thinking about expanding your loop to GPUs.
Oh and I didn't think about X99, that might be possible too.

Honestly, I think the OP just wants to play back video...
 
There is absolutely zero need for complete overkill like this then...
All he would need in that case is a fast enough CPU, a GPU that can output three streams of 4K video and a ridiculously fast storage setup...
 
An entry level Mac Pro would do this job very well. You could build something similar to it if you wanted to... Also, there is no need for workstation graphics in particular, but the Mac Pro has them, partially for their color output and the ability to actually run multiple 4K displays without issues.
 
[sarcasm] On that note, how about an Alienware Area 51? It can run all the latest games at Ultra on triple 4K screens! [/sarcasm]

I'd get a H-240X, another rad, 2 970's(and waterblocks for them) and overclock your CPU and graphics cards like a beast. That's what I'm gonna do at least.

This leaves a lot more room for upgrades(new CPU);

I'd get a cheaper CPU like the 4440 and get a better video card.
And maybe a NH-L9i to save on space.
