COD and iMac

[kstab]

I am about to buy an iMac.

I am interested in the 21.5 model
(CPU i5@2.7 8 or 16 GB RAM and GPU NVIDIA GT 640M or 650M with 512MB of GDDR5 memory)

I will also install win7 64 bit and run COD.

Has anyone tried COD in a similar configuration?

Do you think it will run smoothly @ 1920*1080?

Some MacBooks use intel HD 4000. Do you think COD is even playable with this GPU?


Thank you in advance for every answer.
