Installing graphics card on new build

hi, im new to this so please excuse my ignorance. Tomorrow i will be receiving my mb, ram, cpu, and graphics card and putting it all together. Im sure ill have lots of questions and it might help to show my equipment so here it is:

GIGABYTE GA-MA770T-UD3 AM3 AMD 770 ATX AMD Motherboard

G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333

AMD Athlon II X4 640 Propus 3.0GHz

And the graphics cards is :ZOTAC nVidia GeForce 210 512 MB DDR2 DVI/HDMI PCI-Express Video Card


So here is the question:my motherboard does not have a built graphics card on it...when i put it all together and turn it on...will the graphics card work enough to be able to install the os? How does this work? Thanks
