Hi, I have set up an IP camera system with 17 Geovision cameras (models GV SD200 (1piece),EBL 1100 (13 pieces) and BL 2410 (3 pieces) and I am planning to install 10 more (EBL 1100)) .I use the multicam NVR software (version 8.5.9). The NVR is PC-based with the following specs: CPU: intel i7 4790 - 3.60GHz RAM: 8 GB DDR3 Power Supply 650W Mother Board: ASROCK H87M Pro4. I would like planning to upgrade the PC based NVR with a graphic card. Can you suggest me a suitable one?Would you suggest me make some other hardware updates? Thank you in advance for your help.

Firstly, thank you for your reply!I have already set up a WD Purple hard disk. My problem is that sometimes there is a picture break when cameras are live. Do you have any ideas why this is going on?
