You can see a list of processors with that criteria using ark.intel.com
For your convenience you can use this URL:
Keep in mind that the processor/motherboard compatibility will depend on the motherboard manufacturer, so you need to check with them to see what processors listed there will be compatible with the motherboard you would like to use.
I really appreciate your answer, but the problem it's not the supported motherboards brands or where to find them, they have put them out in the market pretty fast! The problem isn't the Intel Tool to discover the processors either. My main problem is that I cannot find them in the market. From the June 29th and today, I found one retailer that has ONE xeon v3 LGA 1150 (the 1275). What makes me think that they are coming out very slowly and I'm opening a business so I'm kind of "in a hurry" that's all.
All the best,
