DVDSP on new iMac or keep current PowerMac

Question

Perhaps this sounds like a silly question, but then again, perhaps not...
I currently have:
- Dual 2.0 GHz 64-bit PowerPC G5;
- 2GB 400 MHz DDR SDRAM;
- 2 250GB Serial ATA 7200 rpm hard drive;
- AGP 8X Pro graphics slot;
- ATI Radeon 9600 with 128MB DDR SDRAM;
- 3 PCI-X slots (one 64-bit 133 MHz, two 64-bit 100 MHz); and
- 8X SuperDrive (DVD+R DL/DVD±R/CD-RW);
- Firewire 800 & 400
- USB 2
I also have an external HD and a DVI 19" monitor
Question: Would the new iMac be faster then my PowerMac?
I use the computer for normal everyday applications, but I also use the following programs often:
- Final Cut Pro HD (4.5)
- DVD STudio Pro 3
My thinking is, I can sell my MAC and have plenty of money to purchase a new iMac. If I sold my monitor with it, I would be even better off.
What do you guys think?
Would the new iMac be faster?
Would the new iMac be better for video editing?
Looking forward to your thoughts...

Answer 1

Don't forget that the version of FCP and DVDSP are going to have to run under Rosetta if you get the iMac. This is going to make the iMac run them at far lower speeds than the PowerMac will. If you choose to upgrade to the Final Cut Studio when the Universal Binary version becomes available, it might be a wash, performance wise. I personally prefer the expandibility and upgradability of the PowerMac. You may want to wait until Universal Binaries of FC Studio become available, and see how the speed is before buying a new iMac now.
And to DVD Ninja, it's spelled "Camaro". Just a pet peeve of mine.
