Need Help!

Hi,

I'm new at hackintoshing and I have some questions about my system.

Mobo: Asus P5K

CPU: Intel Q9600 @ 3.58ghz, 4 cores, 4 threads

GPU: Msi GTX 970

RAM: 6GB Random ram @ 800mhz

​

I know that Nvidia cards don't work on catalina or mojave so I'm trying to run High Sierra, I have it all installed and it's working, except, not very well, my gpu is stuck at 800x600, I can't install drivers because I can't get my ethernet to work, it randomly reboots sometimes.

​

If you can help me, please reply, I am hoping to get into hackintoshing but my pc isn't that good.
