This is probably the best PC I have ever built. A lot of parts went into it. I had issues with the NZXT X61 so I moved to the Noctua NH-D14 which I had laying around. I then decided on SLI after I found out Best Buy sold Reference GTX 970's. The Noctua NH-D14 did not allow for me to have a video card in PCI-Express Lane 1. I had to go back to water cooling but luckily the Swiftech H240-X came back into stock from FrozenCPU.
It currently runs stable - 4.4Ghz @ 1.25v. Temps are a little high on the CPU but I do have the pump/fans sent to "Silent" via the Motherboard. Both video cards are overclocked to 1250Mhz on the GPU Clock (Boost goes up to 1457Mhz) and 1950Mhz on the memory. Graphics score of 25335 on FireStrike.
