I am planning my next build and stuck between the i7 3820 or the i7 3770.

What are the pro's and cons going for one over the other?
 
there is not much in it though there are a few surprises. Are the differences noticeable? and roughly on a corsair H80 or H100 cooler, would I get 4ghz or more?
 
I use it for everything from desktop apps, FTP and web design
to games. Flight sim to GTA and also processor
intensive games like football manager.
 
Yes the 3820 will do over 4Ghz, but the 3770K is a marginally better CPU for less initial outlay. In your case the only point that confuses things is that the LGA 2011 socket has some degree of future proofing, whereas the LGA 1155 socket is on its way out. For the uses that you've listed I think that LGA 2011 is overkill, but it is Intel's enthusiast platform, and judging by your sig you fit that description quite well.

Personally I'm waiting for Haswell to arrive before making any upgrade decisions.
 
My last build is a Q9550 on a P5Q-E board. This has lasted me 6 years and is going well in to its 7th year. On one hand it will still do the job, but I am gradually being left behind.

I don't upgrade my cpu that often. 4-6 years or so. So I could future proof as best as I can with the 3820 or I can say the 3770 should be good enough to last. This is the sticking point. What I will also say is that I have a gtx 480 SE. It is likely that in a year or so I will upgrade that to a £200 - £250 card then.
 
LGA2011 option costs more and to be honest most people won't see the benefits of hex core CPU, extra PCI-E lanes and quad channel DDR3, so IMO money is better spent on 3770K and just put the saved cash towards a better graphics card in the future. Unless money is no object and you just want the absolute best of course.

Yes LGA2011 has upgrade options but at the moment it doesn't seem like Ivybridge-E chips are going to be much better than current Ivybridge. LGA2011 haswell chips are likely to be very expensive and you will most likely be able to get mainstream k version haswell with decent mobo for the same cash anyway.
 
cheers.

So its between spending £££ and clocking a cpu to 4.0ghz or over, or, spending even more £££ and also clocking a cpu to 4.0ghz or more. I intend to keep this set up for 4-6 years again, the next build will be whatever technology is current then. I am not too worried about being able to swap out a cpu for the latest fad. I guess then its the 3770K. Will have to wait about 6 weeks until I can afford this.

By which time we will be another 6 weeks closer to the launch of Haswell... ;)

Not saying that you should definitely wait, just saying it's worth keeping in mind especially if you don't intend on upgrading again for a long time afterwards.
 
lower temps is good and yes the Haswell is due but when it comes out it will push down the price of older tech. Ohh such a hard decision.
 
I would opt for the 3770K or wait for Haswell, both of these support VirtuMVP as well so you have added benefit of being able to use the integrated graphics in conjunction with a dedicated card for improved FPS in games.

The 8320 on the LGA2011 platform like everyone has said does have an element of future proofing and an immediate upgrade path, but no integrated graphics, if you were going extreme it would be the right choice. But for me the 3770K on the Z77 platform outperforms it, has the benefits mentioned above, is built on the newer 22nm process and if your keeping it for 4-6 years LGA2011 will be superseded by then anyway, so for you I see only the 3770K as a contender, and overall it's cheaper, win win.

What is the difference between the ivybridge E and K chips?

just picking up a little misunderstanding here,

ivybridge-e isn't out yet, those will be the hex core/above socket 2011 processors. They will be overclockable (I imagine)

the 3770k is the 'k' version of the 3770 (both standard ivybridge) for socket 1155. k is more overclockable than non-k
