Any advice for a non gamer who just wants a high end office computer mostly for stock trading. I have a DELL 360 workstation now with a 2.8 P4. Would like to buy or build a computer that is not a HOT box very little noise and faster than what I have now. Building my own would be fun. DEll has USA support for the 390 workstation. I have used it and it was great very little wait time. Thank you for any advice.
