I had an RX480 8GB blower card that I sent back to XFX for an RMA. They sent me a "new" replacement card because the blower card was unrepairable. The replacement card is a dual fan RX480 8GB black edition, which I assume is better than the blower card for cooling anyways.
I ran userbenchmark on it, and the GPU shows to be slightly above expectations (67th percentile?) so I try to run DXMD to test it out.... and I encounter my first problem.
The game loads up fine! For about the first minute on the main menu, then I get a completely blank grey screen and the monitor says "no signal" but I can still hear the game running in the background. CTRL+ALT+DELETE sometimes gives me my display back, but sometimes it doesn't so I can't kill the game and need to reboot.
Since this has been happening each time I run the game, I tried ripping the DisplayPort cable from my GPU and connecting it to the onboard APU (4790k). This actually works and my display turns back on immediately! What's even better is that despite now running off my APU, the game is still using the GPU to render, and it may be at 98% usage in task manager but it runs and I get 30-50fps on ultra.
What I don't understand is why my screen dies out on me in the first place, and why the APU is able to handle the load and my "new" GPU is not. If I run the game from scratch while plugged into the APU, it will give me shit framerates (2-7fps on ultra) but it still RUNS. It doesn't kill the signal to my monitor.
What I have tried:
The only reason I think the signal is being cut is because the GPU is nearing full load. However it should just give me poorer framerates or choppyness, and not kill the signal entirely?? I've never had this happen in a game before. This only occurs if I try to launch the game above a 1080p resolution, or above medium graphics. For comparison, my old blower card was able to handle 1440p at high without killing the display.
What else could I be missing here? I originally overclocked the new RX480 about 5% without issues and thought that maybe that's why the game was crashing, so I changed everything back to stock and it still kills the display. I really don't know what to try at this point and I would hate to RMA the card I JUST got a few days ago because I feel like there's a fix. And it's not like it gets super hot anyway, it kills the signal to my display at about 65c. That's quite warm, but I wouldn't say it's "crash immediately unstable warm". When using the APU I hit almost 80c and it still "runs".... So what's up here?
I'm also aware that in Windows 10 you can run off an APU, and have certain applications set to use a discrete graphics card, but I'm on a much older build of Windows 10 and this feature was not available. And I wouldn't want to use my APU by default anyway, just a thought.
My original RX480 warranty expires in 2 weeks so I'd like to get this sorted before then in case I do really have to RMA this 2nd card... Thanks guys!

What I have tried:
Updating AMD drivers
Rebooting
Clean install AMD driver, DDU
A different DP cable
APU graphics (which works)
A different DP port on the GPU
Changing game from Ultra to Low settings
