Sorry if this isn't related to The Walking Dead:

i have no idea what to do about compoopers or desktops whatever:

my mummy(lol) is letting me get one for christmas what do I do!!!!

I want it to play every sims 3 game (all expansions and stuff packs) with no lag

I don't want specific computers(desktops watever) as im buying in store and need to do it fast, they have a half price sale since the company is in debt and they need to sell stuff off, so yah please give specs and graphics cards and process okay thanks!!!!
