Hi, I want to buy an iMac for photo editing (ca. 75%, Photoshop CS5) and video editing (ca. 25%, Final Cut Pro). I can spend up to $2000, maaaybe $2200. Of course, I'm happy to spend less than. Screen: I understand that I would benefit from the 27" screen a lot, so I'm going to opt for the bigger screen. Memory: Getting 8GB Crucial RAM for 60 bucks seems like a no-brainer. 16GB is crazy expensive so I'll pass on that. Hard drive: I could get the $1700 model ($1600 on Amazon) and save some $$$ or get an external 128GB SSD (I don't want to risk voiding warranty by swapping the internal HD). Would I benefit from the SSD more than from the better GPU or CPU? GPU: This is basically 512MB 6770M vs 1GB 6970M. OR even 2GB 6970M upgrade. Is this necessary? I've heard that the 1GB 6970M is 70% faster than the 6770M but I'm not doing any gaming nor will I be using any other types of 3D software. CPU: 2.7GB i5 vs 3.1GB i5. I could upgrade to the 3.4GB i7. I'd see some video rendering time improvement, but Photoshop is more important Thanks for taking the time to read and helping me out!
