Just been offered a single 1.25 MDD the very last Version. Mainly want it as an upgrade from my 500mhz g4. I use the G4 for Photo editing(Canon 1D MARK 1-circa 2001) and some audio work. Ive been wanting the upgrade and have been thinking about a G5, but this G4 is £40, and the G5 i want is £195. Is it worth picking up the G4? I want to run small amounts of ProTools and Adobe CS. maybe Lightroom 1. Will it handle it all?
