Re: Need some advice on picking a PhysX card

I play and stream PUBG. My primary GPU is a GTX 1070 FTW Hybrid. Since PUBG is built on the Unreal Engine 4 it benefits from a dedicated Physx card. At first I used an EVGA 1050 ti 4Gb single fan card, but since it wouldn't let me use it to stream at 1440p from OBS to twitch, I upgraded to an EVGA 1060 SC 3Gb card. I didn't take hard benchmarks, but while using the 1060 3Gb for Physx and for streaming 1440p60 to Twitch @ 9k bitrate, I've noticed a significant boost in my minimum frame-rates and average frame-rates. The 1050 ti provided an increase too, but it was no where near the 1060 3Gb. I'm considering using the step-up program to trade in the 1060 for a 1080 ti, and using the 1070 for Physx and streaming, but I suspect that the 1070 as a Physx card won't provide any significant advantages over a 1060 for this specific purpose.
Linus Tech Tips did a video to explain why using an older card as you suggested might actually lower your performance rather than increase it. I don't have enough posts to link to the video, so search on youtube for the title, "PhysX Cards - 10 years later do they still suck??"
TL;DR for a dedicated Physx card get a 1060 3Gb everything else is a waste or worse.
