I've got laptop I had used for work in the past that was pretty decent at the time of purchase, but I need to upgrade the video card for neuroimaging software. This is the model I have: https://www.newegg.com/Product/Product.aspx?Item=N82E16834314703 The GTX 860M just isn't cutting the mustard for the 3D brainwave mapping software I'm trying to run. What's the best graphics card I can cram into this thing without something melting or exploding? I'm comfortable with swapping stuff in and out of a desktop, but I've never even attempted poking around inside a laptop due to having so little space inside. I'm concerned about space, heat, and power requirements.
