Upgrading the HP Pavilion HDX X16-1040US. I don't think this will be necessary for a good while but I'm just curious. The laptop has 1 Expansion slot. It says the card slot is 54 or 34, which I am assuming is the size of the slot. (Don't quote me.) Can I use that slot for a physics card? Can the laptop even support a physics card? If I ever found the need to, would I be able to swap the graphics card that comes with the laptop for a better one? If so what slot type should I be looking for? Like I said, I honestly don't think I'll have to upgrade for a lil while cause what it comes with is already state of the art status. But I'm curious. Thanks guys!
