Need Help With Motherboard Selection

looking for some feedback with a new mobo. My 2 choices for motherboard were the ASUS Maximus V LGA 1155, and the Gygabyte GA z 77 UP5 TH LGA 1155. Both are gereat gaming boards with aggresive pricing and I was just concerned wich is best, or however feel free to give a sugestion to a motherboard that (1) has the same or close price to these two boards (2) is LGA 1155 and z77 chipset.  

so far i have

i5 3570k

1 and only one gtx 670 4gb DDR5 memry

corsair vengance 16 gb ( 8x2)

and a cougar 1050 psu 

 

I like the gigabyte because of the 2 thunderbolt and the 2 bios. Also it has plenty of usb 3.0

I like the maximus because of its better cooling, and look XP, its also nice because of the sound.

 

 

BTW: this is a gaming rig.
