I have one DELL 3415W right now as my off screen (which the graphics card lower framerate on to 30hz or something to be able to use it) and an old 1920x1080 screen which it can only run as high as 60hz (this is what I want to change to another 4k... maybe the same as my off screen). I think my power supply is big (1KW).
I run windows 10 on an Intel Core i7 CPU X 990 3.47GHz with two SCSI disc (256GB SSD + 1.8TB HD). I wan't to upgrade my GTX 580 graphics card so it can handle 2 4k screens at the same time, but can I do this?
If yes, what would be a good choice? I am a hardware noob so let me know if anything else is needed to answer the question.
