Because of the limited budget, I plan to buy a second-hand Mac machine for digital photo editing with Photoshop CS3 and Canon DPP. It is surprising that the pricing of PowerMac G4 (MDD, dual CPU 1.25 GHz) is about 350$ and the Mac mini (Core 2 duo 1.86 GHz) is about $400 or so in our country. Is PowerMac G4 still worth buying compared to Intel based CPU machine MacMini in terms of 2D graphics application? I am wondering if anyone or studio still using PowerMac G4 or having experience of using both machine? Would you please share your experience? Thank you!
