Budget GPU options for 390 SFF

My GTX 1050ti ended up being a Chinese knock-off and was shot. I'm still newer with matching components etc (this is my first upgrade/mini-build to get a taste for building computers) Anyways OptiPlex 390SFF i7-2600 16GB DDR3 (2x GB) 1TB HDD (possibly ssd upgrade today) Windows 8.1 I just need a gpu. Right now I am not worried about this being a hardcore gaming PC - For now I am thinking anywhere from $50 - $100 range...Part parts budget took some of the PC's budget haha. Does a gpu in this price range exist that's compatible with my 390? Or maybe something used? Ultimately for now I'd just like it to be better then "factory" Low profile I guess too. I found the GTX 730? 2gb?...Any help appreciated. Thanks guys
