[Solved] GDC Beast vs PE4C 2.1

So a good friend of mine purchased the GDC Beast and found it doesn't work with his machine. However, I have a GTX 770 and a HP 2570p, a hardware configuration that is known to be compatible. 

What is the downside to using the GDC Beast? I've heard that it cannot handle a Gen2 link.

You want a PE4C 3.0 or a Pe4L 2.1.

Both use a soldered cable that's been found to give a more reliable link than any adapters using socketted cables such as EXP GDC or PE4C 2.1. Those socketted adapters very often require downgrading the link to Gen1 speed via BIOS setting or, if unavailabe, via eGPU Setup 1.30 software.

I can downgrade to Gen1 via the BIOS, but the 3.0 and 2.1 are both very expensive (upwards of 200 AUD) considering the small performance gain. Since the GDC is only $30 AU through my friend (I will need to buy a EC cable for it however) is it good for the money?

When I tested my PE4C 3.0 + 2570P + GTX770, it would still very occasionally glitch. I never tried putting aluminium cooking foil around the cable or isolating the power of the eGPU gear to only one socket to mitigate that.

Given the price differential I too would probably grab the EXP GDC, do the above steps and hope for the best. "She'll be right, mate". $200 is getting near TB3 enclosure price which offers 8 to 16 (respective to Gen2 and Gen1) times more bandwidth than your candidate solution.  TB3 then starts looking like great bang per buck.

Hello. First post in this new forums
I would like to ask if there is still a stability advantage for AMD cards over Nvidia.
And if that's relevant for choosing a gpu for use in a EXP GDC.
Its's been a while since I read about that.

I found that with an unreliable eGPU adapter, NVidia will report "NVidia driver has stopped responding" whereas AMD cards will work but with diminished performance. I favor NVidia's superior DX11 performance and Optimus accelerated internal LCD mode feature for narrow x1 mPCIe/EC links.
