Desktop System

[CIncyHR]

Hope this doesn't get posted once a week, but I tried a search and didnt turn anything up.

Right now I'm 4 tabling on a high end Dell laptop (no overlap). I'm sick of PC's and want to sell it to buy a Power Book (i need the laptop for school) but then wont be able to play poker (from what I understand virtual PC is useless for the serious player).

So I was wondering what is the absolute minimm requirement for running poker on a desktop PC? I wil be needing to run two sites (I plan on increasing my # of tables, so I wil need a second party skin) PT, and playerview I will also need to run two monitors. So what system requirements are the bare min for me, and whats the cheapest place I could by one? Any good dels on ebay? Elsewhere?
