New computer for photo editing

Hello all
I was hoping to grab some advice around a Photoshop specific machine. Below are the specs i have come up with as a potential build. Could i please have your opinions on it, is anything overkill? is anything not highly spec'd enough?
In particular is the graphics card suitable, and what sort of monitor should i look at (dont want to spend more than $300 aussie dollars)
I am not a professional photographer but will using machine for Photoshop/lightroom music playback and internet only.

Cheers in advance

Q8200
4GB Ram Kingston
ASUS P5Q SE R (on-board sound?)
Seagate SATA 500g
Seagate 160gb (for scratch)
1GB 9500GT Gigabyte (this has openGL which is good for photoshop CS4?)
SATA DVD drive
Antec Sonata III (case and PSU)
64bit Vista
Monitor????

Basically spend as much as you can afford. That's what I do anyway.

I would upgrade the harddrives if I were you, 500gigs is pretty small nowadays.

More people will probably respond to the post you made in the computers forum, as that's the right forum to post questions like this to. A mod may lock/remove this duplicate thread.

Whoops this is a duplicate post, can anyone advise how i have it deleted?

Cheers
