Upgrading my current i7-3930K (and other components) to a faster system

[jschultz0614]

I currently have a 1500 Watt 80 Plus Silver Thermaltake PSU, 2 EVGA GTX 680 video cards, 32gb Quad Channel RAM and an I7-3930K Proc. My motherboard is an ASUS Rampage IV Extreme (not 2011 r3). I am wanting to upgrade to:

• 
  4x EVGA GTX 1080 TI cards
  
  1x Intel i7 4960X proc
  
  64 GB Quad Channel memory (2x 8x8gb kits)
  
  1x Creative Labs Sound Card
  
  1x 2tb Seagate SSD
  
  and appropriate water blocks from EK Web.

My PSU only has 4x PCI-e 12 volt rails and the current video cards are using 2 rails each.

So my question is, Do I need to get a different PSU or an additional ATX PSU?

Your psu is sufficient.

What is this upgrade primarily used for?

If you want 64gb 4 channel, buy a single 4 x 16gb kit.
Disparate kits are not likely to work.

I do not see this as a very effective upgrade, you now have a i7-3930k with a passmark rating of 11985 and a single thread rating of 1935.
A $800 I7-4960x has a rating of 13800 and a single thread rating of 2079.

For $550 or so, you can buy a i9-9900K with a rating of 20174 and a single thread rating of 2900.
In a decent case custom liquid cooling is not necessary.

Yes, you will need a good Z390 based motherboard and ddr4 ram.

Also, for a high performance system, consider using a Samsung evo m.2 pcie ssd.
The sequential performance is some 4x better than sata. Yes, it will be more expensive.

I currently have my system water blocked. The system will be for Gaming and work. I want the 4x video cards so I can cut the load on my existing cards. So upgrading is not a good path. If I replace the MB, it would have be the ASUS Rampage Extreme VI or the Maximus. BUT, I HAVE to have 4 PCIe-16x/8x slots and an PCIe-2x for the sound card.The Processor I am looking at is a hex core 3.6 Ghz.
