I initially planned to purchase Black Ops for Mac from the Mac App Store for my late 2009 iMac. I was thinking I'd then buy GameCompanion and connect an Xbox 360 controller to my computer, effectively making it an Xbox.

The exact card is the ATI Radeon HD 4670 256 MB. If I did purchase the game, would I notice a severe amount of dropped frames, making gameplay really frustrating? If so, are there quality settings in the game I could turn down? Also, could the use of a wireless controller create additional lag? Any advice appreciated.
All machine specs are as follows:
