I want to upgrade my GPU (probably to a GTX 1660 or a 1660TI), but don't know if it will fit in my motherboard (which is a asus P8H61 M le) and if it will fit into my new motherboard which I am planning on getting sometime soon (Asus ROG STRIX H370-F). I am still learning about PCs (as you can probably tell), any help would be greatly appreciated. Thanks.
