A couple of issues.

1: That nforce 590 Mobo is kinda gimped re real overclocking. Other than change the multiplier, any changes (fsb, ram frequency, timings) have to be changed via software (ie ntune).

2: Dell allready uses the 680 for the 720. XPS700 and XPS710 owners (of the regular air-cooled variety) have allready been sold 680s as "upgrade packages" to rectify the rather indifferent performance of the 590.

Well, that's one big issue really. The watercooled/peltier thing is a neat gizmo, but the air cooled one already worked well. It's a big show to hide the fact that they don't have a real quality btx mobo. Yes, these are all btx by the way, so forget about upgrading it later. the whole system will have to be thrown away in a couple of years, unless the dead form factor makes a magical comeback.
