I know very little about graphics cards. The one I'm using (came with the computer) is a Nvidia GeForce 9600 GS (not the GT). I'm thinking about upgrading to the Radeon HD 7770 but I'm wondering if it will even work.
The old card (9600 gs) is PCIE 2.0 and the 7770 is PCIE 3.0, will it still work? My power supply is a 350 Watt, and the 9600GS was a 400 Watt minimum, will the 7770 still work? The 7750 takes no power supply consumption (look it up) and the 7770 is only 1 step up..... ?
