I recently bought a couple of 290s and looking to upgrade my cpu and board.

I am considering the 4820k because of the 16x/16x pcie lga2011 lanes for the 290 crossfire.

But I've read that 4770k is faster but only will use 8x/8x for crossfire.

Cant find a definitive answer on whether the 290 saturates a 3.0 x16 lane.

I can buy them at the same price, the 4820k is cheaper by $20-30.

The CPU itself maybe cheaper but the 4820K setup can potentially cost you more money since there are $140 motherboards out there that can run and overclock the 4770K just fine. A solid X79 motherboard starts around $250 and just gets more expensive.
 
You wont see an increase in performance with the x79 and multiple GPUs until you get to quad setups. Even then the performance increase is minimal.

Thanks for the input! Im definitely considering the 4770k. Just waiting on more responses before pulling the trigger.

I would be spending $200 upwards on the board whether I pick up any of the cpus.

If the cost for the board + cpu would essentially be the same, what cpu would be better?

I was in a similar situation, ended up buying a 4820k, 4770k setup is not that much cheaper to what people actually think, and the thing is a damn space heater. lol, but both are good
 
4820K isn't always faster than the 4770K in dual GPU setups. In fact, sometimes it's slightly slower depending on the game.

The problem is that a $200+ LGA 1150 motherboard is more than likely going to be of higher quality than a $200+ LGA 2011 motherboard. A $300+ LGA 2011 mobo will more than likely equal the quality of a $200+ LGA 1150 mobo. SO there's still going to be a cost-difference unless you're the idiotic type to spend $300+ on a LGA 1150 mobo. In those idiotic cases, the 4820K would be the better setup.
 
I would go with the 4820k setup, maybe $100 more but you get better temps with the 4820k (enough reason for me)

Better temps? That makes no sense what-so-ever. The 4770k is an 84W CPU while the 4820k is a 130W CPU. Therefore the 4820k is going to dispense more heat into any given area than a 4770k.

TIM soldering is bad on the 4770k, may you can check some reviews and compare?

I don't have to check anything to know that the 4770k runs hot due to that issue, however the 4820k still dispenses MORE thermal energy into the room than a 4770k. Max temperature is meaningless in that regard. Even a 4770k running 80C under full load will dispense less heat than a 4820k running 70C under full load.

well, I prefer 4820k running at 60c with higher thermal energy over 4770k running at 70c with lower thermal energy ;)

Doesn't really matter to me as long as you're aware that your 4820k @ 60C will heat up the room more than a 4770k @ 70C.

How could it heats up the room more with lower temp?
It is more power but the temps are better absorbed so the 4770k will heat the room more because overall temp will be more. But the higher thermal energy on the 4820k will just increase the electricity bill.
It is like you get something without any cooling on it with lower thermal, it will get hotter than the other thing with higher thermal energy, and better cooling.

What you say is technically right but in real, the 4770k will "heat" your room more because of the TIM fault.

Yeah I didn't think you would understand.

You are wrong. The 4820k will heat a room more than a 4770k.

Let me show you some examples.

You know those old, but still in use, incandescent light bulbs? The filament inside them burns up to 5,480 °F but your room isn't getting anywhere near thousands of degrees F or even hundreds of degrees. Why? Because the thermal energy of them are around 40 - 150W. Can they raise the temperature in a room? Sure, but not by much. Obviously a 40W light bulb is going to heat a room less than a 100W light bulb, yet the filament inside both burn at up to 5,480 °F.

A candle's flame can burn up to 1,400 °C, but are you going to use a candle to heat up your room? No. Because they don't put out much thermal energy at all despite having a high temperature.
