[glowpurple][glowpurple]SP2, YES OR NO ?[/glowpurple][/glowpurple]

Hi there fellow members

I have SP1 with all neccesary updates. I play a few games online such as Americas Amry ops and other games through steam? I have downloaded sp2 but don't know whether to install it over my working sp1. Can anyone that has installed it give me some advice on how sp2 differs from sp1. Any advice will be appreciated.

Thanks
