I'm going to build my first pc and after some research on the i7 2700k they said that the i7 2700k does not support PCI Express 3.0 x16. But i've seen people with the 2700k and GTX 670 in there build and sometimes in SLI.
So im wondering will my pc work if i use the 2700k and the GTX 670 together?

CPU: Intel Core i7-2700K Sandy Bridge 3.5GHz
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

My mobo is a GIGABYTE GA-Z77X-UD3H
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

and the GTX 670 is EVGA 02G-P4-2678-KR GeForce GTX 670 FTW 2GB
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I intend to overclock the 2700k to 4.5ghz to 5.0 ghz and cool it with the h100.

I won't get a i5 3570k cuz i also want to video render/editing and multitask alot.So don't bug me and say to get a 3570k. I just need to know if the i7 2700k can support pci-e 3.0 x 16/GTX 670. Later on i may get another GTX 670 to sli.

No it doesnt support PCIe 3.0, it will let you SLi 670's it just does so at 2.0 not 3.0 spec which currently is irrelevent anyway. If you want 3.0 support get a 3770K

The Sandy Bridge chips all support a maximum of PCI-E 2.1. There really isn't any kind of major performance difference between the 2.1 or 3.0 yet, but maybe by the time there's Radeon HD 9990s and GTX 890s it might matter lol.

However for not much more then that i7 2700K you can pick up a i7 3770K which is slightly faster per clock (10%-15%) and it also has PCI-E 3.0 support. http://www.newegg.com/Product/Product.aspx?Item=N82E168...

$30 dollars well spent in my opinion.

Will it decrease fps and by how much? games like skyrim, crysis 2,world at war, metro 2033, bf3, batman AC. plus i intend to record and edit video and multi task. IF i overclock my 2700k to 5.0ghz or more it works almost the same as the 3770k overclock to 4.5ghz.

at the most, a few frames. theres almost no difference between the two at the moment.

A 2700K overclocked to 5GHz would be bit better then a i7 3770K, but even with a great cooling setup, 5GHz is far from guaranteed. Ivy Bridge is the newest tech, even if you're an extreme overclocker it doesn't make a ton of sense to get a Sandy CPU right now as they are about the same price. Right now there is absolutely zero performance difference between PCI-E 3.0, and PCI-E 2.0, even with the best video cards available.

However at one point PCI-E 2.0 wasn't any better then PCI-E 1.0. Now we can see some difference with Radeon HD and GeForce GTX cards from the last few generations.

By the way, an i7 2700K is exactly the same as an i7 2600K but with a higher multiplier. It's not even binned higher, so if you're intent on getting a Sandy Bridge CPU, grab a i7 2600K and save a little cash for a nicer case or more fans.

My recommendation though is to get ready for the future and get an i7-3770K.
