GTX 550 Ti Glitches Artifacts

[insomniack]

I am having artifacts on the screen. Installed Sierra 10.12.2 and web drivers. It starts after I install web drivers. It all starts just after the boot no need to run a software. Using the same build with windows installed and no problems. Trying to fix that weirdness with graphics before coming to USB and Audio.

Components are;

 

Supermicro X10DAL

Dual XEON e5-2658 v3

GTX 550 TI

 

Sending my config.plist and DSDT in attachment. 

Appreciate for any help
