Guys, I've always been a Windows user but am wanting to switch over to Macs as they're just so much cooler! However, the PM with display is a bit out of my reach so I'm thinking of buying the new G5 20" iMac and either adding in a 1GB RAM stick or even 2 1GB RAM sticks (and getting rid of the 256Mb one that comes with the machine). Is this going to be able to do what I want to do? I'm mainly in to using Photoshop and I'd also like to do some fairly decent DV editing in Final Cut Express. Will the iMac be able to handle this well? I'm currently using a 1GHz P3 laptop with 512MB RAM which is fine for PS but DV editing is appalling. Will I notice a huge improvement using the iMac? What is the ideal RAM to install? Is 2GB overkill or the best bet? Also, I've read some threads about using an external hard drive for the DV work. Is that a lot better than using the internal 250GB drive? Many thanks in advance!
