[mustcan]

Hey,
Am using
i5-7400
Gigabyte Z270X Ultra Gaming
Corsair 8Gb 3200Mhz
700Watt Bronze 80+
Rx 580 8Gb
Nvme XPG 6000

Currently im using Rx 580, but i want to using it dual Rx 580 8gb.
Is it any good??

How much fps ill get in game? And how well its perform to editing software?

Very much dependent on the individual software you'll be using.

Vast majority of games don't support multi-GPU set ups, which is why most recommend a single powerful graphics card. Only a handful of games support multi-GPU set ups.

With respect to editing it again depends on the software you'd be using. And even then, the CPU may play a role in how well it runs.

If you narrow down the scope of 'games' and 'editing software' I'm sure someone can provide the info or at least point you in the right direction.
