I don't see an issue here, the GPU will slot in just fine.Ok, my wife's gone crazy and is starting to build a PC around a MSI Z370-A PRO, adding good stuff all around (core i7-8700 3.2GHz, G.Skill RAM), but for a couple of months she will have to use my old PALIT GTX 660 Ti as a GPU.
Will that work without a hitch? I know nothing about GPU compatibility - I mean, I know that I can physically plugin the card into the mainboard, but my question is - should I?
