Is it possible for this card to run far cry 5? My niece had a pc built and they put in older stuff and her graphics card keeps crashing, she can only afford under 200. I was looking and it should be 256 bit but this card is only 128, not sure if that will make a difference if she sets everything to normal or low. Thanks for any help!
The RX 550 and GT 1030 are really meant for less demanding games HOWEVER if you're willing to make some sacrifices you can run a game like Farcry 5 on it.
Specifically, you'll want to think about running at 720p instead of 1080p. You'll need to lower some settings, possibly to as low as they can go. Finally, you'll need to be happy with framerate in the 30-35fps range.
For a card like that, 2gb is enough. I wouldn't spend extra for 4gb unless it's a negligible amount. An RX 460 or 560, or GTX 1050, would be a significant step up in performance but the cost goes up too. I assume her CPU is good enough.
