I know this isn't the question from before but I might as well ask. I was told by the retail guy that if I wanted to get a 1070 or higher, I would need more than the 600W that my present PSU provides. Is this actually true?
Also, should I pay attention to anything in particular when trying to figure out if the GPU would fit in my casing. My current Radeon R9 270 fits fine I think, but I read that even the way the ports are placed on the card can cause issues when fitting it in.
