Do you have any experience in building computers?

you could get an absolutely blinding computer for £500 if you build.

And a few more questions:

Do you overclock?
What is your monitor's native resolution?
What are you going to be doing with it?

I'd definitely recommend a build. Use a firm like Aria or Scan and compile a whole build on there. I've design a 4gb ram, 160gb HDD, 3Ghz C2D, 9600 GTS, with a 19" monitor and XP SP3 shipped for around £500, and that was just briefing through the site, i'm sure i could scrimp even more if i tried.
