I've been looking at cards lately and saw an evga GeForce gtx 950 ssc 2gb gpu I was wanting to get. My question is will it fit in my case? I believe the specs for my pc say it's a mid size atx case. Also, it says it's an internal atx 460w psu. Would I need to upgrade that too? If so, how many watt psu would run it well? Thanks for any answers, looking to get the card today if I can find out whether it'll fit or not.
