Just make sure your computer has all the necessary hardware to run the Sim software. You may want to check out the system requirements specs before you decide on any of them. You may find that your computer isn't powerful enough, or has a good enough video card to run this software. And even some of the good video cards are not compatible with their software.. so check things out before you buy.

When I upgraded my PC recently, I made sure that it had the right capabilities to run the sim software. Strange.. buying a PC to match the software rather than the other way around. Tells ya who is in control here.
