I have just purchased a used HP ProDesk 600 G1 SFF for £80 (i5-4590, 8GB RAM) and am looking for a cheap (likely used) low-profile GPU to match up with it to use for a bit of light PC gaming and emulators. I was thinking of a GTX 1050 Ti, but prices seem to be somewhat inflated at the moment. Does anyone have good alternative recommendations that would be suitable?
