I recently (a month back) went through the choosing the best performing value HSF thing and spent far too long looking into it!
after some time I found the the next step up in performance from the Hyper 212+ or Evo were these :
Thermolab Trinity Ultra-Quiet - £34.98

Cooling a 150watt heatsource = 15c over ambient @ 50.6db
Zalman CNPS10X Performa - £26.71
http://www.frostytech.com/articleview.cfm?articleID=2498
Cooling a 150watt heatsource = 16.6c over ambient @ 58.7db
Coolermaster Hyper 612 PWM - £34.99
http://www.frostytech.com/articleview.cfm?articleID=2644
Cooling a 150watt heatsource = 15.1c over ambient @ 50.7db
The Trinity cooler is a nice choice as it manages to perform so well while not getting as large as the 612.
The Thermalright TrueSpirit 140 is an excellent cooler I would choose over any here in this list I think, but gets into a higher price bracket.
If you plan to overclock your 3770k to about 4.5GHz any of these coolers should be fine. But if you want to go for the max you can squeeze out of it you will want something better, going into the TrueSpirit 140 and better territory. Those Ivy chips start producing much more heat fast going about this speed+ and the vcore that will be needed.
If spending that kinda money then you might as well get the best ones out there which more or less come down to:
Noctua NH-D14
NZXT Havik
Phanteks PH-TC14PE
As they have the headroom to cope with heat pretty much all other HSF's get thermal runaway from. I almost bought the Trinity cooler for my current set up (which being an older 6core chip I felt I might need that extra cooling performance) till I saw the following review covering most of the coolers we are talking about :
NZXT Havik vs Noctua NH-D14 Review
Well, I hope my accumulated experience from Many hours of trawling through reviews etc help a bit. That review basically sums it all up for whatever level of cooling you think you will require and money you want to spend
(I bought my Noctua NH-D14 from ebay for about half the normal price, are lots of Great coolers on there from those buying water cooling setups - while folding@home with sig setup I am running at only 55c, very happy with this!)
