OMG!!! I'm on a mobile phone, looking up stuff takes a minute and doesn't refresh the page when you back up, so excuse me for posting 7minutes after you finally decided to announce that all you needed was a cpu, mobo and ram.
You've not said purpose, need, budget. There's a big difference with using the pc as just a web browser - light gamer, in which the cheaper i3 would be perfect, to using the pc for heavy gaming - rendering videos for a YouTube channel in which case the i7 would be much more desirable, but costs over twice the price if the i3. You've also not stated if it should be a locked cpu such as the i5-6500 or if it needs to be unlocked for OC such as the i5-6600k.
The more parameters you give, the better and faster you'll get answer.
Making ppl who are trying to help, guess at answers through lack of info because you refuse to give parameters is not only pedantic, it's also down right irritating and a waste of everyone's time.
For all we know, you really need a motherboard that supports native M.2 slots, because your current C drive is a Samsung 950 Pro, so using a h110 mobo is absolutely useless. For all we know, you are running SLI, so most cheaper boards will be useless as they only support Crossfire, it eliminates most mATX and all the Itx boards since they only have 1 pcie x16 slot. Get the hint.
