[X-Unix] Memory G5 -?

[CP]

Good morning folks.

I know having as much memory as possible is always best, BUT… I 
currently have 1.5 GB's and I'm wondering if more would help running 
some of the following applications, or if the system will allocate as 
needed.

G5 - 2.5GH'z
10.3.6

Most drawing app's
PhotoShop CS
Final Cut Pro HD
GoLive
Netscape
160 GB main drive
250 GB 2nd drive
External case with;

160 GB drive
120 GB drive
80 GB drive
and a second external 160 GB drive in it's own case.

Many of these, I'll have launch at the same time so… can I expect a big 
difference if I got more memory?

Oh, I'm asking because it does seems slow at times, but then again, it 
seems much slower then I thought it was going to be???
