Thats not really the case at all. You define your price range, look at the cards nearest the top end of it and see whcih one is the fastest in the games you want to play. If he's spending £100 on a card the main features are all going to be the same except for DX10, which at the current point in time actually creates a FPS loss so buying a crapper card because it has a feature that'll make it run even worse is quite a retarded approach. If you have to buy a card now, its gotta be an x1950... unless you can wait till the geforce 9*** series comes out and the price of the current 8800gts's comes down to the £100 mark.
