Hi all, I'm new, I want ask you something: I'm looking to use an external gpu on my laptop, I have see this type of adapters: PE4H-EC2C-060B (gen 1-2) and PE4L-EC060A (gen 3). I think the last one is the best for use next gen gpu. The question is: it will work on my laptop? I have an Inspiron 1750 with gm45/gm47 chipset, intel mobile 4 express gpu -.-. The laptop have the expresscard slot, i'm using it with an usb3.0 adapter. Please answer
