Intel no longer makes desktop boards. You can visit any of the motherboard manufacturers (asus, evga, msi, etc.) and search their board products, or you can view some of their desktop offerings here: http://www.intel.com/buy/us/en/catalog/desktop/all Intel Shop
There are a lot of reasonably good deals around for 4th generation Core i7 processors (like the i7-4770K and i7-4790K). The 6th generation part (i7-6700K) is also reasonably priced as well though motherboards for it are slightly more expensive (as is DDR4 memory). For the budget conscious, there are equivalent Core i5 and Core i3 parts as well. I would note that, the newer the parts you use in your system, the longer you will have before compatibility issues arise (I am including the Windows O/S in this category). Thus, my recommendation is to look at the Core i7-6xxx, Core i5-6xxx and Core i3-6xxx processors.
As for motherboards, you can look at the primary ODMs' products, like Asus, MSI and Gigabyte. They all have high-end as well as entry-level (budget conscious) motherboards...
Hope this helps,
