Rx 480 crossfire question

Here are my system specs.


Amd Fx 9590

Gigabyte 990fx-Gaming motherboard

Corsair H115i

16 GB Corsair Vengeance Ddr3 1600

2 Gigabyte G1 Rx 480's

2 Crucial M4 SSD's in Raid0

Evga Supernova G2 1000w PSU


So I know a lot of games don't scale very well in crossfire but my question is about the games that do.


Since my video cards are PCI x 3.0 and my board is only 2.0 is that going to affect my crossfire performance.

The crossfire doesnt seem to be working correctly most of the time.
