There are only a handful of motherboards which have compatibility for ASUS Thunderbolt EX3 PCIe card. The ASUS X99 Deluxe II would work but I like SLI/CrossFire configuration of the Rampage V Extreme better. Also, the M.2 slot in the Deluxe II is for vertical installation for some reason.

The new motherboard will arrive later today. I'll work on putting everything together this weekend. The Alienware Area 51 R2 will be running with the following specs:

  • Motherboard: ASUS Rampage V Extreme
  • CPU: Intel i7-5820K (Overclocked TBD)
  • RAM: 4x 8GB DDR 2400 MHz
  • Boot Drive: Samsung 960 EVO NVMe M.2
  • GPU: GTX 980 Ti Hybrid/Radeon R9 Fury X

My Alienware Area 51 R2 is up and running with the new motherboard! Here are some pictures of the MB swap process.

Removed original motherboard and relocated two plastic cable holders out of the way for the E-ATX board

Fitted ASUS Rampage V Extreme board and made sure alignment was good

Added the essential components to the new mb

All was in place and ready to go

It booted it up! No smoke or burnt smell. Grin

I'm in the process of installing drivers and will report back whether Thunderbolt 3 is working on this new board.

Success! It took a few BIOS updates and playing around with the Thunderbolt settings in the BIOS but I have Thunderbolt 3 running on this desktop. I paired it up with the AKiTiO Node which has the lastest firmware. Take a look at CUDA-Z screen captures. I'm really confused now. Maybe I need some sleep and get back to this in the morning. Grin

Internal 16x PCIe 3.0

External TB3 4x PCIe 3.0

I will be running more benchmarks this weekend. So far, Unigine Superposition showed very little difference (4%) between internal PCie slot vs. external TB3 enclosure. The two GPUs I'm using are identical in terms of specs and age. This is as controlled of a comparison as possible.

Great job. You must use the same GPU so you can put the GPU in Node when you test TB3 and put it back in the Desktop PC when you test PC, we wait for more benchmarks and especially Heaven (you can try with different resolutions 1080p / 1440p and 4k) to vie if PCIe vs. Thunderbolt thread will confirm the 20%performance drop for 1080p and less for the 1440p and 4k on external display or it is less like your first benchmark! 

But use the same GPU not two models because the clocks are different, the cooling are different etc...

Thank you for the hard work and the time you spend testing eGPU performance!

Superposition (EXTREME 1080p) benchmark is very strange as i have better results with my eGPU even on INTERNAL DISPLAY with Thuderbolt2 vs. Desktop PC:

Superposition through external TB3 4x PCie 2.0 GTX 1060 (eGPU) Thunderbolt2 @16Gbps | MacBook Pro (Retina, 15-inch, Late 2013)

Superposition through Desktop PC 16x PCIe 3.0 GTX 1060 (Desktop PC) @126Gbps ( )

Superposition through Desktop PC 16x PCIe 3.0 GTX 1060 (Desktop PC) @126Gbps ( )


Superposition (HIGH 1080p) benchmark shows lower results (10% performance drop) with eGPU on Internal Display vs. Desktop PC because of higher FPS, that confirms again that lower FPS = less performance drop or even NO performance drop!

Superposition through external TB3 4x PCie 2.0 GTX 1060 (eGPU) Thunderbolt2 @16Gbps | MacBook Pro (Retina, 15-inch, Late 2013)

Superposition (4k Optimized) show us again near to no performance drop of eGPU on Internal Display vs. Desktop PC - Amazing:

Sweet!! It looks like we have a nice bench machine to test with!! You r a genius!!

Agree. Should be the same GPU.

How you could try the TB3-CPU vs TB3-PCH now?? There is any way??

To clarify, the pair of GTX 980 Ti Hybrid GPUs I'm using is identical in specs and age. In the BIOS, I can assign the Thunderbolt card to either connect directly to CPU or the Southbridge. At the moment, it's connecting through the Southbridge (PCH).
