I am planning to upgrade my computer but I am having some money issues. I currently have a Gigabyte R9 270 installed and I wish to crossfire another of the same card. Is this possible while using both of the card's Maximum power? It says on their website but I am doubting it cause of its such low price. Can someone please help me?

Thanks for you help, guys!

No, i do not recommend crossfire on this board.

This board has two PCIE X16 lanes :
1 PCIE 2.0 at X16
1 PCIE 2.0 at X4

This means crossfiring two GPU on that board would result of a double PCIE 2.0 X16/X4

The least acceptable would be 2X PCIE 2.0 X8 as it would already bring a 5% performance loss And from what i read, PCIE X16/X4 has a performance loss over double X8 ranging from 2% to 25 % with an average of 10%

So you would not get an as good boost as you think since motherboard restriction. Also, what is you Power supply ? to make sure it can handle it.
