I am in a holding pattern and needs some advise. I have the opportunity to buy the iMac 413(1TB HD, 4gb ram, HD4670 video $1408.00) or the 950 (500 gb HD, 4gb ram, 9400m video, $1104.00) My biggest question is which of the two has the best graphics card? I want to be able to play games like Modern Warfare 2, and others, and also do minor photo works. What is everyone's thoughts here?
