i am a freelance art director/designer and have gotten my money's worth out of my dual 1.0 ghz MDD G4. it's showing it's age and i definitely need to upgrade. i'm just wanting to get the most value for investment dollar on a G5. don't want a MP right now. so i guess i've narrowed my choices down to either a G5 Quad Core 2.5 (seen them obtainable for around $2000 or so) or one of the Dual Core (2.5, 2.3 or 2.0). basically, am i going to get $1000 of performance difference from say the Quad Core 2.5 to the Dual Core 2.0? i usually have about 6 or 7 software programs and browsers open at a time. i do a lot of back and forth between the adobe CS2 suite, acrobat, safari, suitcaseX1, itunes and MS office. i've been watching on ebay and other sources and have generally found these price ranges for each: G5 Quad Core 2.5 - $2000 and up DP 2.7 - $1600-$1800 Dual Core 2.5 - $1600 Dual Core 2.3 - $1200-$1400 Dual Core 2.0 - $1000 my gut says spend the $2000 to get the fastest machine. but if i can get a DC 2.5 for like $1500, and the performance isn't much difference, i may do it. even further, if i am going to have to upgrade to a MP or whatever else comes along next with intel, maybe it isn't worth it to put so much into a G5. any thoughts or advice folks?
