So im trying to upgrade a very old system a dell optiplex gx520 and wait before you start complaning on why im spending money on this pc, let me tell you that at some time im gonna sell this pc so it has to be able to run something at least, on the mean time here is my problem the pc has one pci (not express) slot at the very bottom and i want to populate it either with a gpu mainly for gaming or deep learning (just ligth stuff) or a wifi card due to its location i dont have easy access to a ethernet connetion, both im gonna take advantage before selling but wich one its more viable to buy you know for resale because the gpu can give you better graphics and the wifi card more flexibility
Edit: im gonna change the procesor for something like a pentium or a core 2 duo so by any means i dont spect to run something like crysis
