My plans are to purchase a barebones unit with only the power supply, motherboard, and CPU. All other components will be transferred from my old unit. (20 gig HD, modem, CD drive, CD/rewrite.) All components are less then one year old. I plan to use dual monitors and will purchase new video cards as needed. The unit will be for trading and also for running accounting software such as quickbooks. I see in the archives that the asus P4C800E motherboard is the most often recommend. Is this the best motherboard? Or is it overkill? Which CPU is the best for this combination? I know there's been some talk about this recently, but I'd appreciate the help of those with more knowledge then I have on the subject.
