Will the entry level 21" iMac play Total War?

I am basically wondering if the entry level, 21" iMac will play the more recent Total War games (Empire: Total War and Fall of the Samurai) on a high setting. If not then how well will they play?
Also is it therefore better for me to spend a bit more money and get the next 'level' of iMac?
Thanks for your time.

Please do not crosspost the same question more than once and in one forum. Thank you! I merged your questions together.

The entry level iMac should be sufficient to play most games even those that are graphic intensive. Of course if you can afford it, the better iMac with more robust graphics and the extra VRAM would be even better.
