Hello friends,

I have 2 280x (gigabyte rev 2 and saphire toxic), but my mobo is a z87m-plus.
So the mobo only have 1 pci-e 16 and another x4.
How much i will win if i change for 2 pci-e 16x?
Today what is the best mobo for crossfire (2 pci-e 3.0 x16)?
And i wanna know the cheapest mobo with the 2 pci-e 3.0 x16?
