Can i crossfire rx 580 with a 550W power supply or get new GPU

[shahed154]

I have a 4gb RX 580 right now and i want to invest in a new gpu or get crossfire so i can do 4k smoothly. 

But i do have a problem i only have a 550W power supply 

Idk if it can handle 2 580's or should i buy a whole new graphics card like a 2070. 

SYSTEM SPECS:

i5 8600k (coffee lake) 6 cores

gigabyze z370 i think xd its cross fire supported 

adata sx8200 480gb m.2 ssd

1tb wd blue

rx 580 4gb 

8gb ram 

550w gold power supply

what are your full system specs?

Buy the 1070 or 1080 if feasible. Forget crossfire and 4k with 4GB cards.

 

You pretty much need a 2080ti for smooth 4k at this time if that is your goal.

 

But to answer your question, I don't think a 550W power supply is enough. I have an 850W unit and I used to crossfire R9 280, and the system would shut down during heavy gaming in certain games. I checked it out and it wasn't thermals. Sooooo...

but for the 2080ti has alot of driver issues, he (or she) could get 2 1080ti's in SLI

SLI/Crossfire is sh*t and has bad support. Better get 1080Ti/2070/Ti.

Depends on the game he is playing I guess. Crossfire bit me kind of hard because it was just a poor experience. Games would flicker, some games didn't support it, TONS of more noise and heat. Dual wielding doesn't seem worth it in my opinion. It's a great idea... but yeah

^ this. Constantly. It's hard to disagree with from my experience.

[aezakmi]

I had a 1070, now a 480 xfire, similar performance but double heat and consumption

 

this has been the worst trade deal in the history of trade deals

What GPU you looking to get ?

Kinda curious myself.

 

I have a CF setup, and I must say, I'm pretty happy with it, but my philosophy is, if you wanna do CF/SLi, go big.....that is, dual RX VEGA 64/56 or SLi GTX 1080 Ti/RTX 2080/RTX 2080 Ti. Why? Well, in case there's no CF/SLi support, you're still able to run the game pretty well on a single card. DX12 may have developers supporting dual card setups, I play Strange Brigade, which is a DX12 and Vulkan game, @3840x1080, absolute max ingame setting and there seems to be CF support, must be because both my cards are under load of about 90% and my framerate's 130fps and higher.

 

Another kicker with AMD cards is, there're hidden gems in the GPU, one guy at guru3d is tweaking and testing BF V with RT enabled, a VEGA 64 seems to be handling it pretty well enough......still early stage though.
