How to speed up my system? New Grafic Card doesn't change the

[Mark-V-]

Im using Premiere & After Effects (allways actually Versions), sometimes with Photoshop (PSD file). I've got an PC (i9 10900k, 128 GB Ram) on Windows 10.
I changed my grafic card from "RTX 1050 ti" to "RTX 3080 ti". Now i miss the result. I use some plugins only one time (Denoiser, Keying etc.) and the timeline changed to red and the Video can't playback without stucking.
So, there is no really improvement. It's feels like it is the same (like with the rtx 1050 before).
Andy ideas ?

Most plugins are not GPU accelerated in Premiere, hence the red line.

Would it be better to change to an "rtx 5000"? The support told me, that cards (rtx 5000,6000,8000) are much better than the rtx 30-series for video-software.
But in the internet all sides say, that the performance values of the 3080ti (i allready own) are much beter than the quadro rtx5000 (round about same price).
