I'm using the PC primarily for gaming and some audio recording for drums (part-time session drummer). I had some initial issues getting video out to the monitor with a BIOS boot, but found that I needed the keyboard/mouse inserted. However, aside from that, I've had no issues at all. I will say that as a first time builder, the "crunch" you hear when you tighten down on the CPU made me almost have a panic attack.
Please note that the video card I got was actually a ROG Poseidon GTX 780; the specs are pretty similar to the one below. Price was the same. Also, don't mind the cables/mess, I have since cleaned that up and it's running like a charm!
