What's the best PC setup for Premiere Pro?

Or am I in the wrong forum? After 12 years with FCP, I think I am.

I see Walter Biscardi's jumped ship. We've invested a lot in FCP's workflow, with xml-parsing tools and all sorts of stuff that may well have a life on another platform.

We're a Mac house now, but Premiere and Avid both work better on PCs, so we'll be ditching our Macs over time, I guess... any advice? HP or Dell?
