I have a 2009 2.66 QC i5 with 4850 and might buy the 3.1 QC i5 with 1g 6970m provided it actually provides a significant boost in Mac and Windows games (read: WOW and SWTOR).
The other option is to get a stand alone PC with display port output and use the iMac as a display though I am leery of breaking the iMac somehow by doing that.
