Which specific i7 processor? They are now 6 generations of them and most generations require a unique motherboard design.
Also, this forum is for the support of Intel's desktop board products. Are you looking for an Intel board product or just a board that supports your Intel processor?

DX79 series boards supports more RAM, but unlikely you will find any compatible CPU at reasonable price.
Intel went out of desktop motherboards business in 2013.
I am looking for desktop where i can used it for running multiple VMs.
I am looking for board which can support 32 GB atleast..may be will plan for upgrade in future.
Would be looking for processor which can give better performance to support my need.
Based upon the planned usage model, I agree with JFFulcrum. For multiple VMs, you are going to want lots of Cores and lots of memory. I thus believe that one of the Haswell-E Xeon derivatives makes the most sense. The Xeon derivatives support 4 memory channels (instead of 3) and thus can support up to 8 DIMMs that provide up to 128GB of RAM (with appropriate motherboard). Top processors available are: Core i7-5960X (8 cores), Core i7-5930K (6 cores) or Core i7-5820K (6 cores). Asus, MSI and Gigabyte all have top-notch X99 motherboards with sockets for up to 8 DDR4 DIMMs.
Edit: To see available motherboards, go to Amazon and do search with "x99 quad-channel".
