I think both of those will run the Sims 2.
That's actually not a bad price for that laptop considering the screen (for anyone confused, this is Aus$ not US)
The PC specs seem farely average and I think for that price there really should be a monitor included but ohwell.
The PC will run the Sims 2 a bit smoother due to it's videocard being better (although it is still a basic videocard, most of them coming out nowadays are pretty good) but I'm sure the Laptop's Intel 4500MHD graphics Accelerator will do the job good enough for you.
You would really just have to decide if you need portability or not.
