Processor and motherboard support?

[sKata8]

I would like to know about the pricing details of core i5 processors and there respective supported motherboard details.

You can look up pricing for processors here:

https://ark.intel.com/content/www/us/en/ark.html

Intel no longer manufacturers desktop boards,

Using the link I provided, select your processor. Then, select "compatible products" on that page. Then, on the next page, select "find compatible boards".

The list of boards, if there is a list, is not necessarily complete, so you need to explore board manufacturers yourself.
