My New Comp(maybe)

[Skeram18]

So I was wanting to get some advice from other gamers. This is the first comp I have bought myself, but I have built many. Others just purchase the parts. My Q's are based on the mobo, are there any better mobo's out there for some gaming with the setup I have. I mean I want my games to look top notch. So yeah, my indecision and being wary belongs strictly because of of the mobo.
