I have this motherboard and as I don't think it bottlenecks, I know that it is really old and you can't overclock as much as you would on other boards.
Woah! Just from that pic I can see cables flying LOL! Pretty good part choices.

If you could tidy up the cabling a little bit because it would help the parts get cooler and stuff won't overheat as fast but great build
How much FPS do you get in games with the GPU?
