I am going to change my HD6870 to a new R9 390, but I have a doubt, because I seen 2 differents models, one with 2 DVIs and other with just 1 DVI.
With my HD6870 I needed to buy an active DP->DVI so I could use the three monitors.
My newest monitor has a HDMI connection (and DVI), and the two old ones DVI connections. So, I have two options:
Buy a 390 with 2 DVIs (MSI) and continue as now -> 2DVIs for old monitors, and maybe HDMI to HDMI or Active DP to DVI in the other monitor.
Buy a 390 with just 1 DVI (Gigabyte/Sapphire) -> 1DVI to DVI, 1 Active DP to DVI , 1 HDMI to HDMI, this could be done? or it is better the other option?.
