Ok I have a Dell Optiplex 780 with a Intel Quad Q9650. 16gb ram. What I want to know is what the best video card i could use in this system would be. its the mini tower version. also i will need to get a new psu i realize.
Well it seems it has a standard 305w PSU which should be fine for something like a 6570 or a 6670
If you're getting a new PSU then something like a 7850 or a gtx 650 Ti Boost would be pretty good with that system
