i7-2700K vs i7-3770K vs i7-3820

In my budget, I have three different options -- the i7-2700K, the i7-3770K, and the i7-3820. I can pair them up with either the Maximus V Gene or the Rampage IV Gene (depending on socket compatibility, 1155 for former and 2011 for latter), and the total price for each way is about 480 bucks. Here's my comparisons:
Choice a.): i7-2700K
Price tag: 279.99 (Micro Center)
Pros:
-Has 95W TDP, lower than the 3820 but higher than 3770K
-Awesome overclocker
-Unlocked multiplier
-Integrated GPU (if GPU fails, can use integrated for time being)
Cons:
-Almost EOL product
-Not much to upgrade after
-Kinda expensive

Choice b.): i7-3770K
Price tag: 289.99 (Micro Center)
Pros:
-Has 77W TDP, lower than all other processors listed
-Unlocked multiplier
-Newest revision of Intel's integrated GPU
Cons:
-Expensive
-Not as easy of an overclocker as Sandy Bridge
-No more upgrade paths after this

Choice c.): i7-3820
Price tag: 229.99 (Micro Center)
Pros:
-Feature-packed X79 chipset
-Cheap
-Ivy Bridge - Extreme upgrade path
-Somewhat easy overclocking with BCLK strap
Cons:
-Locked multiplier (though can overclock through BCLK strap)
-Processor name doesn't sound as awesome (no K! D:)
-Most power consumption

Main usage: Gaming, editing video (Sony Vegas Pro 11), multitasking

Which processor do you think is best?

I'm looking at some Hot Hardware comparisons, and it seems that the i7-3820 beats the i7-2700K *ever so slightly*; however, many of you guys are voting for the i7-2700K

I am kinda digging the X79 chipset though. (Heheh, I'm Chinese, and 8's in the processor number means something )

The 3930K is expensive :/ and the 3820's cheap (230) :/ and... and...
I don't even.
The 3770K and 3820 average out on Anandtech's benches on tests beaten, but the 3770K beats the 3820 on more of the gamer-oriented settings.
I'm leaning towards the 3770K now...

Sorry! I'm going to be using this for gaming, video editing (YouTube) (Sony Vegas Pro 11), and multitasking.
