Does any one agree that its just mad of Dell and others to install Vista on there Budget PC's. Its just a joke, to run vista with any good results you need, as the bare minimum.
A 128 Dedicated Graphics Card
A 3Ghz or higher processor
A Gig of RAM
If you have less than that, or the manufacture is supplying pcs less than that spec, they should be bundled with XP for sure.
My partners laptop has more or less come to a halt with Vista, and hers is lower than the spec i put above, but its higher than the Windows Spec.
Now mines more than the spec i posted, and its flying...
