Hi, In about an hour from now I will put in an order for some more RAM for my iMac.

At the moment I just have one 1GB RAM chip in my machine. I am in the UK and was planning to go with Crucial. Are there any other manufacturers I should be aware of?

Also, should I spend around £30 for one extra 2GB module or Double that to replace my original RAM aswell? I use photoshop, Graphics intensive applications and also game on Bootcamp.

Thanks
The best manufacturer in my opinion is Crucial. and I'd go for 4GB and max out your iMac :)
