Best CPU for GTX 770?

Solution
Depending on the budget, I suggest a Z87 motherboard and a i5-4670k. If you can't afford that, a H87 or H81 board with a i5-4440.
if you're an amd fan:

if you're an intel fan:
CPU:http://pcpartpicker.com/part/intel-cpu-bx80646i54670k
MOBO:http://pcpartpicker.com/part/asrock-motherboard-z87extreme3
 


So an i5-4670K with a Z87 match would be just as good as i7-4770K? I'm thinking of dual cards and have about $1,200 to play with.
 
Well for gaming, there is negligible difference between the 4770k and the 4670k in most PC. There are very few games where you will benefit from an i7 and that's negotiable because of the $100 price tag. What dual cards are you doing to do? Have you thought about a single, powerful GPU solution?

If you are wanting Hyperthreading, a Xeon CPU would work.
 


I looked at 780 Ti but see a lot of instability issues and the "RMA" used a lot. I'm not going to OC too hard, but I would like to at least a little. From what I keep hearing, it's more about the mobo capabilities. I'm not planning on 3D or anything like that. What is hyperthreading and does it boost performance?
Also, is there any performance differnces between LGA 2011 and 1150? I heard 2011 has more memory capabilities due to bandwidth. I don't know if that's true.
 
Hyper Threading is Intel's technology that enables processors to implement more threads. So for example, the current desktop i5 processors have one thread per core. i3 and i7 processors have the ability to implement HT which allows for two threads per core. HT can be beneficial depending if the software is designed to use it. If the software is not designed to use HT, only one thread will be used to perform tasks. If the software is designed to use HT, two threads will be used to perform tasks thus greater performance. Most games aren't designed/coded to use HT. There are a few that do use it but unless you play those games exclusively, the benefits of HT aren't relevant.

I haven't read about the 780ti issues you speak of so I can't comment on that. I can say that an i5-4670k can support a 780 ti no problems.

As for the difference between the 2011 and the 1150 socket, there are even less games that need the 2011 socket than there are games that support HT. For gaming, the added bonus' don't add up unless you're doing something like 6 screens and 4 GPUs. That's when the more powerful CPU (like an Intel 6 core) might be needed. IMO, the return on the investment isn't worth it. 2011 socket is pretty expensive.
