Is this PC Build viable?

390x2 (eventually two) since it delivers similar performance to the 295x2 at less than half of the costs.

Budget around 1500$-2000$

Use: Gaming in 4K & Digital Art Rendering.

Monitors: 1366x768 HD & 4K Monitor.

Quirks of 2 390x2's, Insane power consumption, aaaand it's an air cooled GPU with two 390 chips on one PCB...

 

I know about the GTX 1080 and the Polaris GPUs are right around the corner, running 4 GPUs seems appealing to me and I also like the idea of this build being future proof with perhaps Crossfire and SLI becoming more powerful and optimized for in the future (Perhaps with an API).

 

I do have a list of questions though,

1.  Will a 1600W PSU be able to power two cards each with a TDP of 580W and 8 8pin connectors.?

2. Will the Motherboard I have support two Triple Slot PCI-E GPUs?

3. How would I possibly be able to cool two of these beasts?

4. Each card comes with a jack to hold them up, would having two jacks holding these cards up be viable if I end up having to move it at any time? I don't want it to snap off. (and yes the jack is required to keep the card in the slot XD)

 

I am new to PC gaming and this is my first build idea I have come up with. Since I'd like to game in 4K (preferably at 60fps) and want to have a future-proof build this is what I've chosen.

 

A photo of what the card looks like plugged in and on a Motherboard from HARDOCP's review of the card is provided below for reference. Also the cards power & temps.

Having two 390x2's seems really exciting to me (to the point of being my "dream" PC) but I slightly fear that having two of these beasts will be too much of a hassle or may not even be possible, so I'm asking here since I don't know that much about PCs.

Okay... This build is stupid now. Get a single 1080, it will outperform the cards you mentioned easily without raping your electricity bill. You won't get scaling and optimization issues anyway and the case wont actually melt. Running 4 GPUs is not viable, it's a waste of money and the only thing you get out of it is bragging rights and an empty wallet. Do SLI with 2 cards maximum. To answer your questions, yes, a 1.6KW PSU will power two of these cards and yes, you will be able to fit both of them.

 

And to answer the subject to this post- no, it's not viable.

After thinking about it for awhile, yeah I think your choice for the GTX 1080 or maybe even the new Polaris cards would be a lot better, I'm going to create another build perhaps and re-post.

This killed me, all humor beside thanks for the help mate!
