Hello i'm looking to upgrade my Computer, I am currently running a eMachine Dual Core with 4GB of RAM and a GeForce GT 440. I'm going to upgrade to a Dell Inspiron Desktop i3847-4616BK (Link Below) and need to know if the GTX 650 Graphics card will work. I know that on my current computer i couldn't do much Graphic wise because of the Power Supply. But the GT 440 worked very well but now my processor and even Graphics Card is out of Date. The Dell Inspiron Desktop i3847-4616BK is from the 660 Series so i believe its 300W and someone on Amazon said the GTX 650 will work but won't be sufficient. Now i could go for a Dell XPS 8700 which has a 460W PSU but i don't want the 635 Graphics card and its like $185 more. Any suggestions and can i just buy a 400W power supply and replace the Dell Power Supply?
