You need a decent computer, the only response that provided data you can use is from Pittcanna. His link shows the requirements, he then suggest what he considers the minimum to get. I don't agree on the CPU, but he gave you the most useful information. If what he says makes no sense to you, don't even bother trying to figure it out, just go to best buy and ask one of the kids in the geek squad, they'll sell you a gaming machine that would work. Bring the minimum spec list from the link provided above and just say "I need something that's at least this good, GET ON IT!" you'll be set then.
