Hey guys. I was all set to buy a 24" 2.4Ghz iMac when I realized maybe I should get a 20" 2.4 iMac instead and use the extra dough (plus some extra obviously) and buy a nice 19-23" external display and hook it up using the miniDVI connection. Has anyone done this and had it turn out ok? I'm thinking i'll want two screens because im about to start doing some HDV editing.
I heard that since both the 20 and 24" imacs have the same graphics card and GPU, the 24" has to work a little harder to fill the screen since its bigger. But then there are those that say the 20" has a cheaper LCD, and that its best to get the 24" version. I would think if I added an extra flat panel LCD monitor to the 24", the graphics card would have to double-time-it to keep up.
Am I crazy for thinking this? Or is this a legit argument? I just don't want that buyers remorse thing to hit me. Yuk
I am toying with the idea of buying the last gen all-white 24" to avoid the screen problems that seem to be hitting the new aluminum version. ooooo but I would love to take my chances and pickup the new one
