GA-H270N-WIFI Poor Performance

[sckn]

Hi Guys, I am a newbie hackintosher in here.

First of all, Thank you all guys for your all effort for us. (for Newbies)

I just made a hackintosh system for business --and rarely, gaming--. I just want stability like real Macs. After all those "stress test videos", I felt like a child. So happy and excited.

My system build;
Mac OS Sierra 17.1:
XIGMATEK 600W 80PLUS PSU.
Gigabyte GA-H270N-WIFI Motherboard.
Corsair Vengeance LPX 8GB DDR4 Dram 2400Mhz RAM.
Intel I5-7600 Kaby Lake Processor.
MSI Nvidia Geforce GTX 1050 2GB.
Sandisk SSD PLUS 120GB 530MB/400MB -read/write-.
Thermaltake Core V21 Micro-ATX Mini-ITX Case.

And in seperate HDD Windows. And It's work poorly in Cs:GO (High and Low Game specs give me same performance)

I follow @phlydude's perfect guide for installing Mac OS Sierra. 10.12.5 on my SSD.
Nothing is bad. Everything is work. Except Imessage. -it's my fault I guess-

Guys, I will put there my benchmark results and ask you to help me about what is wrong with my system. It's not stable. So many instant freeze in normal usage.

Thanks for your help already.

Thanks.

They are wrong because you have Nvidia graphics and those three items all refer to Intel graphics.

@P1LGRIM I know it's too much. But, what about my low write speed ?
How can I fix it ?
I've tried forcetrim command for six times. But it's same.
