Crossfire 580's or 2070?

[Winlock]

Im going to be building a new PC soon and i want to know if crossfire 580's will compare to a single 2070 in performance 
im going to be combing it with a ryzen 7 2700x weather or not that matters im unsure

I'd buy the 2070. Crossfire/SLI isn't worth it anymore.

1 powerful GPU is always better than 2 weaker GPUs for gaming.

Neither.

 

Get a 2060/Vega 56 or 64 and tweak them to nearly equal the 2070, or pony up the extra coin for the 2080.

 

IMO, of course.

 

Dual GPUs can be good, but only if the game supports it, and from a power and vram perspective it's a huge waste.

 

In some scenarios dual GPUs are worse performance.

Why not go with VEGA56 or 64, if you can get a good deal on those?

multi GPU is dead, there are only a hand full of games supporting that...

 

My Test Yesterday was pretty disapointing...

Even if comparable in performance in SLI/Crossfire supported games, it is always best to get a single, more powerful GPU. Thermals will be better since the top card in a Xfire setup usually thermal throttles. Also the keyword to my first statement is "Supported" games. Most games do not take advantage of multiple GPUs and you'd find that one of your GPU's would basically be doing nothing and you'll end up with half the graphical performance you were hoping for. Also, Raytracing and DLSS if you're into that.

Single better card is better than two in SLI/Crossfire. I wanted crossfire so bad for so long, and I ended up doing both at some point or another and it just was annoying trying to find games that performed well and were stable and ran without any issues.

2070 will be faster in most cases. 2070 is ~70% faster than RX 580 in games. Very, very, very few games support Crossfire with >70% scaling. 2070 would also require less work to get running well, have less microstutter, will consume less power, run cooler, and will be quieter.
