cm0scm0s :
From all cards tested the Gigabyte g1 was the fastest 980 TI.
Also on that model you can give it 139% power for overclocking with the stock bios.
Also it is cheaper than the Strix
And it overclocks like a beast.
"From all cards tested the Gigabyte g1 was the fastest 980 TI."
I disagree. The strix is the fastest among others :http://techreport.com/review/28685/geforce-gtx-980-ti-cards-compared/7
Among both,
G1 will be most valuable choice.
