ASUS M5A78L-M || Dell 478 Server OEM (with the right PCI expansion, it looks as if the motherboard could actually be used to accelerate compute, much like a Xeon Phi or a Red Rocket)
RAM
8GB Corsair Vengeance LP DDR3 || 2GB Crucial DDR
GPU
MSI 7870GHz || iGPU of the P4
Case
Fractal Design Core 1000 || Dell Server OEM

1TB WD Blue (Win. 7 x64), 80GB WD800 (Linux Mint 16 Cinnamon (Dual Boot)) || 20GB IDE (Soon to be offloaded to a NAS if I ever stop being lazy set one up)

Corsair CX600 || Dell Server OEM PSU (Probably ~300w)
Display(s)
Westinghouse 1440x900, Dell 1280x1024 (I usually use the 5:4 as a secondary, but it is also the primary for the server)
I use whatever the song downloaded as, because audio "Lossless" is total bullshit and I could care less. Also, I hear no difference from FLAC to WAV to MP3 with my DT990's.
Well that depends on exactly you want.. If you want the hands down best of the best, then that would be a 4960X with an ASUS P9X79-E/WS, but that is also way overkill for most everything. What will you be doing with your PC?
I've been hitting 60 FPS at 900p with my 7870 and 6300 at ultra/high/medium settings, VSync off, tuned to my visual quality preference. No issues yet...
My second monitor is run my a HDMI to VGA, and the adapter is so bad that when my GPU (7870) hits ~80C it just stops working and POOF! No more second monitor...
