Hello, I own a iMac G4 Superdrive with a 800MHz CPU, 256MB of RAM, a geforce2 MX 32MB of RAM, and I believe it has a 60GB hard drive. I'm aware that those specs are highly outdated, but I'm a college student and can't really afford to purchase another computer. I have a more modern PC, but I'd rather use mac. So I was wondering if increasing the memory, hard drive space, and possibiliy the operating system would be worth putting money into. Even if I decided to upgrade my imac, I know it won't be a powerhouse. I specifically use my mac for all the basics, but I'll be using photoshop and perhaps other adobe software for school and personal use. So I'm wondering what version of photoshop would perform best on my machine (not the elements versions). I'll also be using blender. So is the upgrade worth it?
