My computer has 512 Mb RAM at present and I am thinking of increasing this to 1Gb. Would there be any advantage in doeing so? My system - AMD 2400XP, MSI KT4V Mobo, MSI FX5600 256Mb Graphics card. I use the computer mainly for Flight Simming but have recently installed an MSI DVD re-writer with a view to "creating" my own DVD's!!
