With the HD 5450 from Sapphire you should have more than enough power for you daily tasks and will even be able to play mainstream games such as World of Warcraft and The Sims. These games don't require the high-end gear of some of the more demanding games out, but if they do have any slow down, the HD 5450 can overclock quite well, which can improve the gaming performance of the card as well make applications that use ATI stream run faster.
