Im planning on buying a C2D MBP and driving it on a 24" Dell 2407FPW. At first I thought hey no problem the 15" MBP's graphics card should do. Then i took a look at the 24" iMac thinking it would have the same graphics card - nope. Now I'm a little concerned, I've never ran an external display before but by the looks of it the x1600 will be pushed a little too much running a 24" Dell. And I noticed there is no option to upgrade the graphics card in the MBP like there once was, unless i missed something? So what are my options here?
