Please does anyone curenly have a dell dimension 9150 with either a 8800gtx or 8800gts working in it. If so what did you have to upgrade etc i have heard mixed reorts but can not find any definite infromation. Im pretty sure i will need a new power supply unit. I dont want to have to get a new cpu etc... Also is there any issue with upgrading a dell psu can i put an atx sli psu in there.
