Hey dude,
I'm in the middle of buying a new PC, so I kind of got used to technical stuff. Not advanced, just the basics.

I couldn't see any specification regarding the video card. That's not good, because it may mean that it is incorporated thus very weak.
Generally it is ok, but the RAM memory (1 GB) is not enough to fully enjoy ToMI. I have 1,5 GB of RAM and a 512 RAM GeForce Graphic card and STILL I cannot play the game on a higher setting than 4 (9 is Maximum).
Basically, get a PC with at least 2 GB of RAM and a good Video Card, preferably GeForce of at least 512 MB.
Hope this helps, but don't take my word for it 100%, ask around some more
Cheers!
