The price is not so good. That's the only reason it's on sale for a few years already, and the fact that the seller won't sell the board separately.
The thing is, I already have G1.Assassin 2 with 3930K. Got scammed, as it was on sale as "everything works", but the motherboard ended up with one of the memory channels defective, and having the latest BIOS which enables Ivy Bridge CPU support, but completely disables the OC features. These boards suffer from bad/overheating VRMs from the factory (it can be partly mitigated by strapping a fan on it i guess), and they tried to "fix" them by decreasing the OC headroom and finally by disabling it altogether.
The Gigabyte's shitty BIOS isn't helping neither. It's a pain to rollback, and need to use not so reliable tools. Also, the IHS on the CPU is visibly bent outwards, but it works fine (stock at least). I'll take the board to the repair shop and hope the channel will come alive (already did all the possible cleaning, and checking the pins underneath), and maybe ask the guy to rollback the BIOS as well, and I'll probably grind down the IHS to even it out.
So, as I'm not rational when it comes to PC and MTB stuff, I want another X79 bundle, to play around and combine parts. If the mem channel is dead, and the rollback fails, then the Xeon would go to Assassin, and the 3930K to P9. I don't actually have the money for anything RN, but I want the damn X79 platform, and I want it to work as intended.
16xx Xeons are probably the most exciting to play with, but still very pricey...
