Which of my computers to run CoD?

[thnp]

Hello Guys and Gals!

Got CoD on preorder and currently enjoying old "Sturmovik" immensely in preparation for the new upcoming baby!

I'm wondering if somebody could give me input on which of my two computers will give the best result with CoD?

I'm a "Maccie" and will run CoD under BootCamp and Win7 x64 Ultimate.

computer 1:
iMac 27" (2560x1600)
i7 (old type), 4 cores @ 2,93ghz
16 GB 1333mhz DDR3 RAM
7200 RPM disk
ATI Raedon HD 5750 1GB DDR5

or;

computer 2:
Macbook Pro 15" (with video-output to the 27", so still 2560x1600 res)
i7 Sandy Bridge, 4 cores @ 2,2ghz
8 GB 1333mhz DDR3 RAM
Intel SSD
ATI Raedon HD6750M 1GB DDR5



Any input will be greatly appreciated
THNP
