Ive just had my 5770 Vapour-X delivered and everything has been installed. Now im pretty new to graphics cards etc, a nvidia 7950GT having been the last card id bought previously and only been playing Counterstrike in the past. Now i see my card has DX11 capabilities. I have no idea what this is, should i download it to play BC2 with? Apologies for my lack of knowledge, thats what im here for though
