Hi, what's the difference between a 3770k and an 3820? After seeing that the 8320 was cheaper than the 3770K I tried to find out what exactly was different and I though I found out the difference ie, that they are basically the same but the 3820 isn't overclockable.

Well now I think I'm wrong in that conclusion because I've found overclocked bundles with the 8320 in it.

So could someone enlighten me please between the difference between those two.

Don't confuse a 3820 with a 8320. Which one do you mean?
 
3820 has a limited multiplier OC, but socket 2011 has bclock straps. you can strap to 133,166, etc I believe, so you can get it upwards of 5ghz with the right cooling and a good chip.
The real difference between the 3770k and 3820 is the socket 1155 vs 2011. 2011 has quad-channel ddr3 RAM. Ultimately, the only reason you would want to go with 2011 is if you need LOTS of RAM. Otherwise, the 1155 is the better (cheaper) option.
 
Did someone tried to benchmark quad channel? For example with realmark?
 
Just be aware that the Sandy and Ivy Bridge Socket 2011 is a dead end, with the upcoming Haswell Socket 2011 being physically and electrically different.
 
3820 has Sandy Bridge architecture, 3770k has Ivy Bridge. Ivy Bridge uses less power and has higher IPC, but in general clocks lower.

Quad-channel RAM does not benefit 99% of applications. The real benefit of quad-channel RAM is the large amount of RAM you can have.

The other benefit of 2011 is the 40 PCI-E lanes instead of the 16 for 1155. Of course, this only matters if you're running lots of RAID cards and/or 3+ GPUs.

As for dead-end, 3770k is already dead end, while 2011 still has IB-E to be released later this year.
 
8320 has significantly weaker single core performance, and multithreaded performance vary between the i5 3570k and the i7 3770k, all while consuming more power.
