New graphics card not working

I have just recently acquired a new radeon HD 7870 to replace my two old gtx 260's. I have installed the new hardware but the monitors are not picking up a signal and I have been trying for hours to fix the problem and nothing has happened. The graphics card has 6 mini DP outputs but I am using VGA monitors, I have used mini DP to DVI adapters which connects to DVI to VGA them a standard VGA cable to my monitors. (I am using two monitors) I tried my old cards to see if it was a problem with he monitors but they worked fine. Thanks for your time.

The problem is that displayport is a digital connection and you can't use adapters to go from digital to analogue (VGA). You need to use converters instead.

One thing is that one of the DVI ports on the new card will support VGA via adapter, but it is unlikely that the other will.
