I assume you wish to overclock this to its maximum tolerance. If you can afford the hybrid and want to geek out at lower temps go for the EVGA.
EVGA Hybrid:
JayzTwoCents got this card to 1484MHz
Gamersnexus got their card to 1514MHz
Gigabyte G1:
Hexus 1482MHz
I personally cannot justify the cost difference for the lower temps achieving similar overclock speeds.
My advice: Stick with the aftermarket custom PCB by gigabyte and spend the ~£60/$100 savings on something else.
