Could I run BeamNG with a GT 1030 at 1050p with med. settings? at around 40 fps at least? Full setup: Asus PRIME b250+ Core i3-6100 12 GB RAM 500 GB SSD (if you're wondering why the GT 1030 it is because the 1050 in my system is borrowed and i need my own now)
Kinda? https://gpu.userbenchmark.com/Compare/Nvidia-GT-1030-vs-Nvidia-GTX-1050/m283726vs3650 Considering that the 1050 is 86% faster than the 1030, you may have to run the game at low settings for 1080p or mid settings for 720p to achieve some good framerate.
If you have enough PSU wattage you should get something older instead. Something like a GTX 960/R9 280 or even a GTX 950 could be found in cheaper prices, while getting enough performance to compete with newer cards.
You will never go wrong with a GTX 1050 then. Great perfomance, low power consumption. I don't recommend a GT 1030 unless you have an older system.
