So far of Z77's that I know will be released I kinda like is the ASUS P8Z77 WS - http://usa.asus.com/Motherboards/Intel_Socket_1155/P8Z7... however I know a few other MOBO's if equipped with IB can also do 4-WAY with the aide of a PCIe intermediary chipset (the question is at what latency cost). Other very interesting Z77's:
I hope EVGA can regain some good prowess in the Z77's, during X58's they were damn good, but once LGA 1155 came about EVGA dropped out of the picture for too long and lost substantial market share.
I do not recommend being an Early Adopter with any of these new chipsets until a couple BIOS revisions, especially after all of Intel's oopsies (P67/H67 B2, SB-E VT-d C1/C2, X79 C0/C1, etc). Since AMD is on the back burner Intel needs to cool their jets and focus on quality. I posted this Ivy Bridge review sometime ago, but after looking at it you too might have a 'wait & see' attitude -> http://www.tomshardware.com/forum/329828-28-bridge-cpus...
Anyway that's my 2 cents. Testing and overclocking results are needed before I can, other than guessing, know which are good, bad or average.
My 'plan' is to wait for the Haswell or Broadwell lines if possible. The PC's will get replaced as the cost (time vs expense) makes good sense, even having available test servers 'pre-testing' is done on PC's so a few hours a month time savings is an easy sale to upgrade. I have no plans for LGA 1155 which I said before its release, but they're a possibility if I needed an X58 replacement. My X79 is for SQL testing and coding -- even in pieces the data sucks up >20GB of RAM and as many cores as there are on the CPU.
