8 Gig

I am upgrading a computer that belongs to a professional photographer friend of mine, it's already got a quad core processor, I am upgrading it to 8GB of RAM then upgrading to Windows 7 64bit, hopefully CS4 will be a bit quicker for him afer this.
I've done this in 3d again, I think it works quite well in 3d, all of the chips appear to be fairly well in focus as they get further away.
