Very bad gtx 970 sli performance

Good to see your scores improved a bit!

The error message with your score and the score itself (I think) still show something's odd with your system:
"YOUR RESULT HAS THE FOLLOWING PROBLEM(S):
Time measuring inaccurate. Results are invalid. (What is this?)".
See http://www.3dmark.com/support/troubleshooting-my-results/#validation.anomaly.RTC_CLOCK_DEVIATION

Never seen that message myself and I think it's a pretty weird one. Probably related to mobo (CPU) settings, isn't it guys?

I would reset the mobo BIOS to default values and start again from there. Please take screenshots/photo's of your current BIOS settings if you are worried about losing any important settings.
