Will Premiere Pro benefit from HIS AMD 7950 Card?

I have a "HIS AMD HD Radeon 7950 3GB", I tried to enable openCL graphics support in premiere pro but not able to(have updated driver of GPU and motherboard, added required .txt file).

GPUSniffer says "did not find any devices that support GPU computation " & premiere pro is stuck on "Mercury Playback Engine software only"

My Question is - Will premiere pro/Adobe Media Encoder benefit from my graphics card? Will it make any difference if I have this graphics card or use integrated one?

Note: I have rendered few projects in it and it utilize 100% CPU but not even 1% of GPU(I am pretty sure I am using GPU accelerated effects).

My System config:

CPU: i7 3770K @3.5Ghz 4 cores 8 threads, overclocked to 4.27 Ghz

Motherboard: P8Z77-V

RAM: 32GB Dual Channel DDR3 Kingston KVR16N11H/8

GPU: HIS AMD HD Radeon 7950 3GB

HDD: 512GB SSD(OS/Programs), 120GB SSD(Project/Media Cache), 1TB HDD(Media files)

System: Windows 10 64

Premiere Pro / Media Encoder version - 2018
