I was just trying to be generally helpful, not suggesting this as a solution specifically to the Sky Go issue, although it would probably resolve the issue for you, I agree the solution should come from Sky.
My point was that just like Sky produces a sub-standard video streaming solution that is not really fit for purpose, laptop manufacturers also produce sub-standard laptops with poor components that are not really fit for purpose, and there is a few tricks to get a really fast laptop for a fraction of the price of a "premium" laptop.
