5D2 to 5D3 worth getting for just IQ improvement?

Hey guys. This question has probably been asked buy i guess i missed it.

I have no problem at this moment with anything my 5D2 is lacking that the 5D3 has to offer. The only thing that would make me want to upgrade is for the gain in IQ (if there really is one)

So now on to my question....

For those out there that have both or have made the upgrade from the mark 2 to the mark 3 do you really see a huge difference at all in the IQ department, which in this case would make me consider selling my mark 2 and moving on up?

Thanks in advance for help/replies...

Not really. High ISO is better. But if the mkII focus system is ok for you, then I wouldn't do it.

Totally agree with David. Not great improvement on IQ for ISO upto 3200 or so.

Keep the 5d2 and the extra money.

I don't see a huge difference in IQ. The real star of the 5D3 is the AF system. It blows the 5D2 in that regard.
