On X79 there are already cheap fully unlocked 6 core cpu's no need for Xeon's....it would be nice to unlock cheap 8 core cpu's...i'm writing these on my e5-2670 on a X79 board. Realistically it's never going to happen It would be nice though...just imagine if you could unlock an eight core you could also unlock the 12 core variant
Not all of them, only the sku's I've listed above. Mostly because they are the same as the desktop equivalent...just more expensive and with some different instructions. The only CPU that have no desktop equivalent is the 1680 v2...but then again you've seen the price.
