I'm not a big PC gamer, but even for everyday tasks this graphics processor was extremely unsatisfactory: it would choke and sputter while trying to run the UberNES screensaver, and throw various errors while trying to edit videos in HitFilm Express.
The primary reason I chose this card is because my ThinkCentre only has a 280 watt PSU, and the GT1030 only uses 30 watts of power. So no PSU replacement required, which saves $50.
I benchmarked using the free Unigine Heaven
It addition to going from an abysmal 5.1 FPS to a more respectable 46.6, all of the aforementioned errors went away.
