Whats the between AMD 780G and 780V ???

i am getting a new system and would like to get the new AMD 780 series motherboard.

But i am confused over 780g and 780v. What is the difference?
Is it only the integrated graphics core?

HD 3200 for 780g and HD3100 for 780v.

Is there any marked difference between the onboard graphics performance between the two, as i am going for integrated graphics alone (no graphics card).

Please HELP!!!!
