Are you saying I should maybe look at a different motherboard?
No not at all. I love ASRock, great company IMO.
It is the APU thing, I just don't get it if it isn't for a small form factor build. That is a whole regular size tower you have there.
You could always upgrade your GFx card but would be stuck with the same GPU that your APU is running if you go with that FM2 socket.
I don't know how future proof APUs are. I have little experience with them and just built my first build with an APU just 1-2months ago.
If you want to keep it cheap then stay with AMD. Maybe get a FX-41XX chip on a AM3+ socket. That could hold you off until getting a better GPU like a 7850 or 7950.
