I have a Dell XPS 420 with a Radeon 5770 Hawk running 3 x 19" screens with Eyefinity. I used this for my flight sim and span the cockpit view over all screens. This works fine.
I have a spare 23" monitor that I want to connect and use this to the display the cockpit instruments and dials on, freeing up my main 3 screens just for the views out of the window.
I have an option to get a Radeon HD5450 of a friend for a few £ and I am thinking can I install this in my Dell XPS 420 and set this up as a 4th monitor. This is a PCI-e card. Will this fit in addition to my 5770? I'm not near the computer between buying this 2nd graphics card so I can't check myself..
