i5-4690k vs i7-4790(non k) and other components

[Fantasietje]

Hello, this is my First Post in this forum and i'm currently looking to build my first pc, but have a couple of questions in choosing components.

My Budget is around €500 for cpu, mobo, psu, RAM, and I have other parts except gpu which i'll get it 2 months later due to personal reasons.

What i've been looking at are
I5 4690k €223
Gigabyte z97x-sli €105
RAM Corsair vengeance 8gb €70
Psu xfx pro550w €58

But then i See a "offer" from a computer Shop (€500)

[Intel Core i7 4790
MSI H81M-E34 Moederbord
8GB DDR3 1600MHz Geheugen
1000GB S-ATAIII 3,5" Harddisk
DVD±ReWriter Dual Layer
Netwerk en 5.1 HD Geluid onboard
Intel® HD Graphics 4600 onboard
Supports Microsoft® DirectX® 11
PCI-express aansluiting voor uitbreiding videokaart
1x VGA, 1x DVI, 1x HDMI
2x USB2.0 + 1x USB3.0 voor, 2x USB2.0 + 4x USB3.0 achter
Luxe M-ATX Minitower Behuizing (zwart glossy)
exclusief besturingssysteem]

I'm now considering if it's really a offer or i should build with 4690k.
The mothermoard from the €500 pc isn't "professional" and i also don't know the Brands and models of the PSu and RAM.

Thanks for your help and sorry for my poor english

If your main use is for multithreaded apps like rendering, then the i7-4790 is a good deal.

If your use is for gaming, then the 4690K build will be better. You can oc the K easily for the faster core speeds which are good for gaming.

I got a i5 and it does a good job and all ,but I do look back now and wonder if I should of went with a i7 or xeon and not sit here wondering ...

If the extra $100 price premium for a i7-4790K is not a big issue, then by all means, buy the i7-4790K.
You get a better binned chip that runs at 4.0/4.4 at stock.
