Well another go at it, it would be nice if they had the better instruction set, I wonder how they will handle the heat without cutting back on clock speed.  I'd stay with the 6 core and not have to worry about it.  I'll have to hope the price stays down.

I wonder if it's 25MB shared, or 2.5MB each. If the former, it's possible for one or more cores to "hog" all of the available cache, starving other cores for memory, but themselves potentially being able to run faster. This would be good for gaming rigs if the running game can only utilize 4 of the 10 cores, but the overall performance could suffer.

If it's 2.5 per core, then users like Freddy (sort of), who do a lot of 3D rendering (but don't use GPU rendering) would see a marked increase in performance across the board.

Hmm so these will work in my X99-S motherboard ?

Dave, I use CPU and GPU at the same time. GPU is a lot faster, but having the CPU 6 cores helping as well does shave time off.

It's nice to know. I do think my upgrade route for what I do would be another GPU before the CPU.

Yes it would be dual GPU but probably not SLI. It would be with a card with more memory as Daz uses a lot of VRAM. But I could still use two cards in the rendering.

   They have been around for a while, I think I came across some monsters when the 5820 came around, Intel had said there would be more hex core processors coming this fall, Newegg has them on sale.

  I think you got a good deal with the 5820,  I'm wondering if the better processing of commands used with the Skylark is used with the Broadwell 6800k.  It cost a little more maybe worth while.
