I am ever so sorry, but it is not possible to upgrade this laptop due to the graphics being delivered by a chip on the motherboard rather than a independant graphics card. This is often the case for laptops below the £1000 margin, even then those machines are also very restricted to upgrades. Gaming on a laptop is a very expensive hobby and you can often get MUCH more for your money if you use the same budget on a desktop. There is no reason why you couldnt then hook the desktop up to your TV and do gaming on a much grander scale.
