So I'm thinking of getting my very first Apple computer and I've been researching the 24" imac. I came across this video http://www.youtube.com/watch?v=FbY1kTP79vc which is of someone playing bioshock on the 24" imac and it seemed to me that there was a refresh rate problem. Whenever the screen moved a little fast, it seemed like the monitor had a hard time keeping up and you get something of a blur and stutter which doesn't seem to be from hardware slow down. Was it maybe just the taping of the video? Or do these types of things happen in FPS games where there is a lot of fast motion on the screen? I definately want a mac, but I'm still weighting the pros and cons of each thanks.
