Will my video card be compatible with my motherboard?

I am ordering a ASUS M4A87TD EVO AM3 AMD 870 SATA 6Gb/s USB 3.0 ATX AMD Motherboard and was wondering if it is compatible with a XFX HD-685X-ZNDC Radeon HD 6850 1GB 256-bit DDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card with Eyefinity. If it is not leave another suggestion below please...
