To put it simply.. No.

Do you need a monitor?
Do you need a keyboard?
Do you need a mouse?
Do you need an operating system?
What will you use the PC for?

I already have a monitor keyboard and a mouse and there is a os in there. The computer is for gaming

Same price as yours with a better quad core processor, graphics card and psu and an SSD. You can just pirate the OS or get it for really cheap on g2a

To be honest I would spend the money on a Skylake i3 purely so you are on the platform ready with DDR4, so that if you need more performance you can just slot in an i5 down the line. I didn't include an operating system as there is really no need to buy one, you can torrent Windows 7 then get the free upgrade to 10 all properly activated.

Z170 board so when you upgrade you have Overclocking capabilities, if you don't need them get the board Biebs suggested.

No reason to spend the extra $$ for the Strix 380 IMO, I'd just grab the $15 cheaper, Gigabyte option. However, I would suggest spending the extra for even a cheap MSI/AsRock Z170 board, this will give you OC capabilities and those i3's have been doing pretty well with not super high end coolers from what I've seen.
