You mad lad !

I am a huge fan of the SLI GTX 780s lol.

@Jon Jon Hell yeah, they can still clap in games that scale well. 140-170+ fps in Battlefield 4 (which is a gorgeous game btw), 110+ in Battlefront 2015, 60-75 (I have V-Sync on in this game) in Destiny 2. Am getting some random crashing though, trying to figure out if that's windows (I'm running Windows 7, BSOD code can apparently be fixed by running superfetch so I set that to auto start), the CPU/RAM settings, or the GPUs misbehaving.

I have gotten the GPUs to 1320Mhz and completed a Firestrike run at that:
 

Better than 69% of all results ( ͡° ͜ʖ ͡°)

won't do 1333Mhz tho, buut this is at 1.2-1.25v. Apparently with softmods to Afterburner, BIOS mods, and some community built tools, you can push 1.35v with no vdroop through these. Probably wouldn't go that high though, the top card does hit the 80s (bottom card is in the 60s).
