I can't seem to get my 480 to do 4k 60hz. Lines flash through, Ive tried 4 different cables, it is a cyber power pc, I took it back once and it still does it. So it must be amd fault. What seems to work for a bit, is if i switch from 1080p back to 2160p, but it still gets the flashes. I reformated installed fresh windows 10, and amd drivers. Tried messing with voltage, stock, lower, higher, and nothing works. Lol great i updated my asus bios and now i get whole screen flashes.

edit: After reading up some more it appears i was correct. This card isnt designed for 4k gaming, or even 1440p gaming at high fps.
Some games don't handle high resolutions well. For example, high resolutions in Trove make most in-game text vanish. If it's fine on the desktop but problems only show up in particular games, it's likely a problem with the game.
What monitor do you have, anyway? And what type of cable are you using to connect the video card to the monitor?
Also, just out of curiosity, if you were running a GTX1060, why did you switch to a RX-480? Their performance is nearly identical.
Also, I would never trust a PC from Cyber Power, not after what they did to my friend's PC a few years ago. It may very well be the way the PC is setup.

As for the OP topic, If i remember correctly Doom was tested running two 480s in crossfire mode in 4k at 60fps. I doubt a single 480 is enough.
My mobo supports crossfire but not sli so if i sell my 970 im surely getting two 480s.
Crossfire and SLI will only work for a game if the game has support for Crossfire and SLI. There also needs to be Crossfire/SLI *driver* support for said game.
Don't go Crossfire/SLI blindly thinking it will solve all your issues or work with every game.

Cyber Power PC says that they don't sell a 700 W Thermaltake power supply. It's possible that they used to but don't anymore, but it's not on their list today. If you don't know what you have, then open up the case and read the label. The brand name and wattage aren't enough, especially for a brand like Thermaltake that sells both pretty good power supplies and complete garbage.
It's possible that the video card is simply defective and replacing it by a different, non-defective RX 480 would fix the problem. It's a recent enough card that it should still be under warranty.
Red lines sounds like it could be a GPU failing.
Your driver will support 4096 or "true 4K" but most 4K TVs and monitors are actually UHD 3840. The PS4's max resolution is, I believe, also 3840.
Easy enough to check and make sure your driver is set to 3840.

In the event that hatefulpeace is not really a troll and doesn't understand that people stab each other over this stuff - good luck with your computer, just go buy that 1060 and game happy with it.
In case of a TV, I meant take the remote control and use it to open some of the TV's own menu so that it fills part of the screen while you're at 4K 60 Hz and seeing if
a) The whole screen flashes, or
b) Only the part of picture that comes from the GPU flashes while the TV's own menu works okay.
With TV it might be a bit more complicated than with a monitor. Monitors usually have settings menu that fills only a corner of the screen, whereas with TV you might end up with full-screen menus.
But if you've tested it with Geforce 1060 using 2010p at 60Hz and it's worked fine like that, then maybe the test I suggested is not that important.
Does RX 480 have same problems when you're running at 1080p? Or do the problems only affect 4K resolution?
