Apple iMac 21.5" - Games Performance

[Apple Knowledge Navigator]

I'm on the verge of getting the ATi 21.5" iMac, but i'm not sure how some of my games will run. The main games I will be running are;

Sim City 4
Roller coaster Tycoon 3
The Sims

You'll have to excuse my lack of knowledge, I'm not an avid gamer Thanks!

I run Sims 3 fine on my iMac, all settings are pretty much maxed. 21.5" ATI should have no problems

my old G5 iMac could play all those games, so I'm sure the 4670 can!
