Choosing a good all rounder GTX670

Hello

Purchase date : in a week or so
Usage : Gaming only
CPU : i7 3770K stock + 8GB 1600mhz DDR3 + Asus P8Z77-V MB + PSU AX750
GPU : must be Nvidia
Monitor : Samsung 27inch (1920*1080)
Preffered site : Amazon , Newegg(if I have to)
Location : USA

-----------------------------
Now I know that :
Asus
Core Clock: 1058MHz
Boost Clock: 1137MHz
Comments : Some people on various forums claim that it has stability issues (probably due to high level of factory OC) + Amazon dosen't sell it

Gigabyte
Core Clock: 980MHz
Boost Clock: 1058MHz
Comments : Looks like (and from reviews) it has excellent cooler , but lower performance due to clocks (compaired to the others) ? in addition , I had good years of experience with GB graphic cards ! like there 8800GT that had Zalman cooler years ago

MSI
Core Clock: 1019MHz
Boost Clock: 1079MHz
Comments : looks like the middle from the 3 , better clocks than Gigabyte , might be less cooling than also Gugabyte ..

Zotak :
Core Clock: 1098MHz
Boost Clock: 1176MHz
Comments : Never had a chance with this company , but clocks (and reviews) highly praise it for performance !! , Amazon dosen't stock it from them directly ...

What do you suggest ?
Thanks
