looking to as the title states to use 4+ screens? is this possible with xfire/sli setups? (can you still use all 4 dp/dvi/hdmi/vga ports on all the cards in the sli/xfire setup?)
I can't speak for AMD based setups but I know most mid to high end Nvidia cards can do 4 monitors on a single card. 1 display port, 1 HDMI and 2 DVI. However Nvidia surround will only let you use 3 monitors for gaming.
i would be using a few screens for gaming, considered a combined setup and not my favorite idea....currently i have a single gpu setup having a hardware bug where i cant add more then 3 screens onto the card.......
i would love to run a few different things on different screens....
was thinking something like the gtx 760/780 for a muti gpu setup with 3 or 4 screens per card
