Thanks, Gnome-Quote from gnome:
The XPS line has "gamer" mobos. Both them and the the Precision line are just fine for trading.
The computer is concerned only with the power to run the video cards, not the monitors... they have their own power supply.
That's actually what I was refering to, albeit a little clumsily. Is the power source on the 3400 large enough to run a couple of decent cards?
