  6. Let me know if you get any results. I will be doing a similar process with a 4770 with a 350 w PSU with a quad processor and 4 gb ram. So if you test it out I would love to know what happened. If you dont I will let you know what I find out when I install it within the next month.
  7. I have a new dell studio 540 (350 w PSU) with a 4770.
