I don't normally air my grievances, but this has become borderline ridiculous. 
 
Brief background:
Bought a brand new 980 TI SC AC2.0 card from B&H Photo in December 2015. I initially ran this card in Windows 10 for most of its ownership, but now I primarily run it in Mac OS X 10.12 (for programming in a Unix environment!). A few months ago, I noticed I started to get 3-4 second random black screens (both on HDMI and DPs), and upon booting up, random "out of range" signal errors despite running everything at stock (Asus PB328Q, 2560x1440p @60hz HDMI/DP -- note this behavior also happened on Windows 10 as well before I transferred over to Mac OS X!). I'm not entirely sure what's at fault: card or monitor. But I wanted to rule out the card as the culprit, so I asked Evga for a replacement card.
 
The grievance:
I got a rather quick response back from EVGA stating that I should check to make sure my PSU 12v rail was supplying consistent 12 volts (it does), to uninstall the drivers via a DDU program and to make sure I had up-to-date drivers (I did). No change, same problems. So I opted for cross-shipping, paid $650 for a replacement and waited for the replacement card to arrive. A few days later, I got the card, plugged it into my system and I got this:

I thought this may have been a Mac OS X driver issue (despite it running perfectly fine on my originally purchased card), so I uninstalled the driver and proceeded to brick my system (my fault). So I spent about 2-3 hours wiping the drive clean, prepping it, installing a fresh OS, and then installing the nvidia driver. As soon as I got to the set up screen: same artefacting problem!

 
I submitted a ticket for this replacement card. They told me they don't support Mac OS X (fine, I get it, Hackintosh's aren't main stream), so I spent about 2-3 hours prepping another SSD and USB drive for Windows 10. Upon installing and running Windows 10 (installed latest Geforce 376.19 driver as well), I got this:

I responded back that this was not an OS problem nor a driver problem, but a defective card. They asked me to send the replacement back and they advanced sent another replacement card after I provided another credit card (thankfully only charged $1). After a week in transit (it only traveled 375 miles from origin to destination, shame on UPS), but I got the second replacement card, and upon installing it...

I was greeted with a jet engine and no video signal AT ALL. Tried all ports (except DVI) and all them were dead.  Thankfully I didn't have to spend much time troubleshooting this card as it was pretty clear that it was DOA. I submitted yet another ticket for this replacement card, and now they now want me to send this second back before they'll send out another...
 
In total, after 2 weeks of: Ticket submission responses, delivery waiting, and 7+ hours of troubleshooting, I still have...
- A potentially defective originally purchased card?
- A defective replacement card with artefacts
- A defective second replacement card with no signal at all
 
Come on Evga!!! What's going on with your quality control!? I don't want any special treatment, I just want a card that works. 

Just to state, for the record, this issue has NOT been resolved...
 
It seems like my originally purchased GPU is about to take it's last dying breath:

Umm, after 3 cards I'd start taking a look at your other components. Do you have the ability to test the cards in another computer? 

Having spare parts or a second system comes in handle for times like this. 
 
It's rare, but i have read where people went through 2-3 RMA's before receiving a replacement that works right.
 

Wow this is a shame 2 weeks 7+ hours.

Hopefully you get this resolved.
