Help with a 2 new builds

hey,

Both desktop must have an i7 and 16Gbs of ram.

Build 1:
I Am looking to spend $2800 AUD, I live in Australia which is AUD. I would prefer the retailers MSY or Umart as they have the best shipping pricing for me. I have all my peripherals and monitors ( 2x 1080p). I play games and use it for computational work for university. I do want to overclock and I don't need an operating system.

I play Battlefield, Arma 3, Fallout 4... , and use MAT LAB.

Build 2 is the same as build 1, expect a budget of $2000 and $800 on a laptop that I can use to play games on low-medium settings.

Thanks for all the help and recommendations on parts / laptop this is my first time posting..

Build 1: http://au.pcpartpicker.com/p/8xds23

5820K
NH-D15
32GB of DDR4 (2133MHz, C15)
R9 Fury from Sapphire
500GB M.2 SSD from Crucial
2TB 7200RPM HDD from Seagate
850W Full mod silverstone PSU
Enthoo Pro

You may want flashier RAM but the NH-D15 will engulf it regardless. The mobo is the only thing I'm not entirely certain about but it has good reviews, so I'd guess it's an OK board. Case might not float your boat, but there's plenty of options with the money spend on it in this build.

Build 2: Remove the Fury from Build 1.

Prices are nuts in Australia.

So Is this just for you, or is it for 2 people?

First build should possibly be X99 depending on the price difference

hey, I should have cleared it up, those are the two options I am thinking off, either a desktop or a desktop / laptop.

x99 adds about $150 AUD.

thanks for the help! yeah its crazy how much things cost here.

A 390 runs about $150 more, so, might not be worth the jump over a 4gb 380

looking at the first build from space cat, I can get 2 gtx970 asus turbo cards for the same price would this preform better?

X99 seems to be the way to go, would an AIO water cooler do better for the same price or worse?

thanks for all the help guys!

as far as pure performance goes the 970s would do better, but the game has to support dual GPUs which most do.

although in addition if you buy a free-sync display down the road, you save money that way with the fury, and the fury is already more than enough for 1080p and even 1440p

Okay thanks or the help.
