£500 to spend on Desktop PC

[frattonstation]

Help!
My current PC spec is, I'm no expert(!):

Intel Pentium 4 3.0gig
Maxtor 40 Gig Hard Drive
Nvidia GEForce 7600GT Graphics
Win XP SP3

What is the best available desktop for under £500 I can get that would be a better spec than what I already have. To be used mainly for home office and gaming use.
Any suggestions would be greatly appreciated!

Couple of questions first :)

1. Would you consider building from scratch, adding to a barebones or want a complete prebuilt?
2. What games do you want to play?

Probably go for a prebuilt this time.
Like to play "Arma: Armed Assault", Call of Duty, Pro Evo Soccer, Battlestations:Pacific.

Plus can I buy a prebuilt from Novatech, without the Keyboard/mouse and screen. Which I obviously already have.

If your going prebuilt then the system jonny linked will be brilliant, go for the pro version with the ATI 4850 graphics card as this will stomp all over any of those games :)

Many Thanks for your advice.
