There are (rumors of) some external boxes (like the ASUS XG station) that will house any single card width PCI-E graphics card, but I've never seen the XG Station actually hit the market. I have seen some competitor's solutions, but at a cost where it would be more reasonable to get a new system.
The main problem is the bandwidth of the expresscard slot. You're limited to PCI-Ex1 and all mid-range to high-end cards are going to be severely capped by that limitation; to the point of it being a waste of money.

So if I bought something from here:

it would work?
If gaming is the reason for the need to upgrade, I suggest you should rather build a desktop PC rather than gaming laptop equipped with mediocre gpu that would last for some time.
