20" Extra 128MB Video RAM = Total 256MB ATI X1600 Might Help Support An External 24"

I'm thinking the extra 128MB Video RAM for a Total of 256MB of the ATI X1600 on the 20" Might Help Support An External 24" better - probably any external monitor will benefit. I'm only guessing though.flopticalcube said:Does the video mem upgrade on the 20" make a significant difference? Apple.ca wants CAD$150 for it, which seems a bit cheeky.
