Hi Richard A second monitor will halve the amount of video ram assigned to the main display and use the other half to display the second.... Errr.... Display!
3D games performance will suffer but it won't present much of a strain for the cpu or the ram, the video card just sees the two as one very wide display. You might need an adapter, either a minidvi to dvi adapter or a mini displayport to dvi adapter, doe nding on your model of iMac. The aluminum models introduced the mini displayport.
