System underperforming extremly

[Leon_0103]

Dear all,

I recently upgraded my GPU from a Readon 7850 HD to a R9 390 G1 (Gigabyte Radeon R9 390 G1 Gaming Aktiv PCIe 3.0 x16)
I did realise that I can push the quality settings on most games a little more up but not as much as expected.
Now I fear that my system is creating a bottleneck for the GPU the rest is:

Intel Core I7-3770 @3.40Ghz - 3.90Ghz
16 GB Ram
Windows 10
and a 550 watt power supply

so now im wondering why I have the feeling that my GPU is bottlenecked

It was just today that i had them both installed into my rig, to test games side to side.
Arma 3 on a Multiplayer match inside a town i got around 39-42 with the 7850 HD, with the R390 i dont even get close to 30.

Or did i simply buy a wrong GPU

best wishes

Completely uninstall all ATI drivers with the old card in place, shut down the machine & reinstall with the new card.

R9 390 has increased power draw compared to Readon 7850 HD.
Your PSU might be not up to it's task to supply R9 390 with necessary juice.

What's your PSU brand/model name?

A 550W Be quiet

I dont get any issues regarding PSU that the machine shuts down or anything like that

And sorry didnt actually mean to set it as solution problem still persists

You need a 650-850 top tier PSU. Check you CPU % and GPU % and MHz while gaming. The GPU may not be running at max MHz if their is a bottleneck or low power.
