I'm going to get an ASUS HD7870-DC2-2GD5 Radeon 2GB DDR5 VGA/DVI/HDMI/DisplayPort GPU Tweak Utilities PCI-Express 3.0 Graphics Card HD7870-DC2-2GD5 Direct CU II for my Asrock Extreme4 z77, but I'm not sure if the heatsink from the card will block any additional ports. Can anyone tell me if the board's gaps between the PCI slots can fit the massive heatsink? Thanks in advance
