Saving money with Crossfire?

[Wallaceman105]

I'm building my roommate a PC, and we've hit a price spike between paychecks, so I'm wondering if we can save a bit of money by getting 2 RX580s instead of a 5700xt.

For context, his use case is Autocad and light 3D modeling, with a little bit of gaming on the side. 

 

 

This is the 580 I'm considering

The core question is what the performance impact of 2 RX580s in Crossfire would be compared to a single RX5700xt? 

Also, if anyone has the time to explain the reasoning to me, I'd greatly appreciate it!

Not worth the time as a great majority of games don't support dual GPU's.

Most softwares to my knowledge utilize one GPU a lot better than dual as well, depends which ones you're referencing though

The software he's going to be using is the Autodesk suite, and the gaming isn't a priority. 

Is there a resource for what softwares work best in which way?

I think those don't support crossfire or sli, so a single faster gpu is your best bet
