I bought an Asus STRIX 980 Ti few days ago and have been feeling like the performance I was getting from it was somewhat lesser than I expected. So I installed GPU-Z and I think I've found out some problem areas.
But as far as I know, it is supposed to be something like this
The GPU Tweak II software that came bundles with the card shows these
Gaming Mode
OC Mode
My build is
I7-4970K
Asus Sabertooth Mark 2
1 WD 2TB Black
1 Transcend 256 GB SSD
Corsair CS650M PSU
I used the two 8 pin connectors on the PSU to power each of the 2 8pins (they are arranged in 6+2 pin style) connections on the GPU
Sorry if my English was bad.
