Old system took a dump, repeated failure to post. Old system had gigabyte 990fx mb with fx8350 cpu. I've went with an asus tuf gaming x570plus mb and ryzen 5 3600 cpu. Was using geforce gtx 950 video card, hope it wasn't the problem, I looked at some replacements. Holy crap, batman! Gotta be a rich man for most of them. Question is because the gtx card would sit right over the fan on the mb chipset if I put the card in the top slot, can I use the bottom pclex16 slot instead? Also haven't been keeping up on computer tech, what the heck is an M.2 socket for?
