i've been thinking about upgrading to nvidia 6 series but i've heard that you need at least a 300 watt power source to run them ius this true? in that case are there any suggestions on good power sources you guys have had experiences with? i attatched my computer's specs. its a dell dimention 4550. thanx for the info -Dan

Dells use custom sized/made power supplies from what i know.. As far as changing it ... Im pretty sure thats not possible.
