Which board good to start out with?

Hello, this is my first build and I don't know a lot about hardware but I hope I can get some help here  . I will be using it for school work and moderate gaming and I want to learn how to overclock with it. I will be getting a athlon II x4 630 and maybe a hd 4850 later on. But right now I am having trouble deciding which motherboard to get. Im stuck between http://www.newegg.com/Product/Product.aspx?Item=N82E168... and this one http://www.newegg.com/Product/Product.aspx?Item=N82E168.... They're around the same price and overall both seem like good boards, upgradable , have good reviews, and they are gigabyte. except the first one has igp and the 2nd one is a full ATX. Are there any disadvantages to getting a motherboard with onboard graphics? I think its good to have in case my video card dies or something. But I dont know if its better to overclock on the one without onboard graphics because I read somewhere that someone overclocked the cpu on a board with igp and the mobo caught on fire. I guess I like the 785g board more but what do you think?
