Low profile GT1030 will be the logical choice. [URL]  
I currently have 2GB ATI Radeon R5 430 fitted to my SFF Optiplex 5050 - which I mostly use for general PC browsing, photo editing etc. But I would like to play some games on it - not that bothered about amazing high res graphics - just a bit of fun playing something older at without lag, like Titanfall, Battlefield 3 or even some of the newer stuff going free on Epic games right now. Can anyone recommend something a bit more powerful that would fit in the same case? Thanks.
OptiPlex 5050 SFF upgrade the R5 430 with something more powerful?
