Overclocking r9 390 and fx 8350

[MightyH]

I have learned that these two shouldn't be bottle necking each other and have had an over clock on them for a while. I am wondering if these are good overclocks for my CPU and GPU given my system specs.. thanks.
I have my r9 390 overclocked in msi afterburner:
Core voltage:+100,Power limit +50, Core clock mhz: 1160, memory clock mhz:1600. Are these good or can did i go to high?
My fx8350 with the 212 evo is OC to 4.5ghz, can i go higher and should i with this being air cooled? My cpu VCORE is set to 1.4375V. Anything helps, thanks. Tying to get the most performance without doing something wrong.
Here are my specs:
Amd fx8350 cpu
Msi r9 390
Cooler master 212 evo
EVGA 800W
Gigabyte GA-970A-UD3P ATX AM3+ Mobo
Roswell challenger U3 mid tower case
AsusVG248QE monitor 1080p 144hz
Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-2133 Memory
WD caviar black HD

Your CPU is probably at max with an air cooler on it so long as it isn't the stock cooler if it is rip it off and buy one. Your graphics card memory clock could probably go higher my 380 is set at 5800Mhz.
