But you can get 700k out of them

Nothing, IB ran hot at launch due to there being too much TIM between the IHS and the die so delidding helped a crazy amount, but any recent chip is fine.
Source: Another thread here and my i5 never going above 80c under my D14 without being delidded.
I better update mine
. I went a bit over but I can afford the $300 or so extra.
The way I'd have the screens is the 21:9 one as my main one with the two 1080p IPS screens on either side, I'd split the 21:9 into two separate ones using the software that comes with it (So it's effectively two 1080p screens without a bezel in the middle) and then use Eyefinity to make all 4 1080p screens go as one assuming I can do that.
The 3820 are the weakest SB-E chips with the worst physics out of them all. Half of the logic units disabled and leaky transistors. It clocks bad and consumes a lot more power. Typically, if you can't afford a 3930K at start you won't for most of the life span of the SKU and when you do there are more efficient and faster mainstream solutions. Unless there's a specific reason why you couldn't get the 3930K.
A proper 3770K can be quite a bit faster. 3770K can get to 4.7 on good air cooling, 3820 about 4.5-4.6. Factor in that 3770K is faster clock for clock (my 4747MHz 2600K was on par with my 4487MHz 3770K) it's really a reasonable difference.
I certainly notice the difference between my 2600K at 4.7 and 5.2.
