I own no shares, and the graphics chip means nothing at all to me as long as the system does what I need it to do, which does not involve 3D games.Yeah, yeah. Just play with your shares and ignore valid criticisms. It's been all over the web this last month how lame a job ATI has done with that video chip.
I'm certain the GPU is more than adequate for my tasks. If gaming's what you're after, get a PC or a Pro, or realize that the iMac will do an adequate job on most games anyway. The form factor is why many people buy it, and shoving a GPU with it's own fan in there would adversely affect that.
